+## 10.0.0
+
+- Stable release targeting Dart 3.2 using new `dart:ffi` features available
+  in Dart 3.2 and later.
+- Add support for ObjC Blocks that can be invoked from any thread, using
+  NativeCallable.listener.
+- Fix invalid exceptional return value ObjCBlocks that return floats.
+- Fix return_of_invalid_type analysis error for ObjCBlocks.
+- Fix crash in ObjC methods and blocks that return structs by value.
+- Fix ObjC methods returning instancetype having the wrong type in sublasses.
+- When generating typedefs for `Pointer<NativeFunction<Function>>`, also
+  generate a typedef for the `Function`.
+- Use Dart wrapper types in args and returns of ObjCBlocks.
+- Use Dart wrapper types in args and returns of static functions.
+- Renamed `asset` to `assetId` for `ffi-native`.  
+
+## 9.0.1
+
+- Fix doc comment missing on struct/union array fields.
+- Allow extern inline functions to be generated.
+
+## 9.0.0
+
+- Added a JSON schema for FFIgen config files.
+
+## 8.0.2
+
+- Fixed invalid code generated due to zero-length arrays in structs/union.
+
+## 8.0.1
+
+- Fixed invalid code generated due to anonymous structs/unions with unsupported types.
+
+## 8.0.0
+
+- Stable release for Dart 3.0 with support for class modifers, variadic arguments, and `@Native`s.
+
+## 8.0.0-dev.3
+
+- Added support for variadic functions using config `functions -> variadic-arguments`.
+
+## 8.0.0-dev.2
+
+- Use `@Native` syntax instead of deprecated `@FfiNative` syntax.
+
+
+## 8.0.0-dev.1
+
+- Fix invalid struct/enum member references due to multiple anonymous struct/enum in a declaration.
+
+## 8.0.0-dev.0
+
+- Adds `final` class modifier to generated sub types `Struct`, `Union` and
+  `Opaque`. A class modifier is required in Dart 3.0 because the classes
+  `dart:ffi` as marked `base`.
+  When migrating a package that uses FFIgen, _and_ exposes the generated code in
+  the public API of the package, to Dart 3.0, that package does not
+  need a major version bump. Sub typing `Struct`, `Union` and
+  `Opaque` sub types is already disallowed by `dart:ffi` pre 3.0, so adding the
+  `final` keyword is not a breaking change.
+- Bumps SDK lowerbound to 3.0.
+## 7.2.11
+
+- Fix invalid struct/enum member references due to multiple anonymous struct/enum in a declaration.
+
+## 7.2.10
+

+
+## 7.2.8
+
+- Automatically generate `ignore_for_file: type=lint` if not specified in preamble.
+
+## 7.2.7
+
+- Fix some macros not being generated in some cases due to relative header paths.
+
+## 7.2.6
+
+- Fix path normalization behaviour for absolute paths and globs starting with `**`.
+
+## 7.2.5
+
+- Add support nested anonymous union/struct
+
+## 7.2.4
+
+- Add new supported typedef - `uintptr_t` (mapped to `ffi.UintPtr`).
+
+## 7.2.3
+
+- Change compiler option order so that user options can override built-in
+  options.
+
+## 7.2.2
+
+- Added newer versions of LLVM, to default `linuxDylibLocations`.
+
+## 7.2.1
+
+- Fix helper methods sometimes missing from NSString.
+
+## 7.2.0
+
+- Added support for sharing bindings using `symbol-file` config. (See `README.md`
+and examples/shared_bindings).
+
+## 7.1.0
+
+- Handle declarations with definition accessible from a different entry-point.
+
+## 7.0.0
+
+- Fix typedef include/exclude config.
+- Return `ObjCBlock` wrapper instead of raw pointer in more cases.
+
+## 7.0.0-dev

+  config file, rather than the working directory of the tool invocation.
+
+## 6.1.2

+
+## 6.1.1
+
+- _EXPERIMENTAL_ support for `FfiNative`. The API and output
+  might change at any point.
+
+## 6.1.0
+

+  of declaration filters to exclude everything, rather than include everything.
+
+## 6.0.2
+
+- Bump `package:ffi` to 2.0.1.
+
+## 6.0.1
+
+- Replace path separators in `include-directives` before matching file names.
+- Add more ways to find `libclang`.
+
+## 6.0.0
+- Removed config `dart-bool`. Booleans are now always generated with `bool`
+and `ffi.Bool` as it's Dart and C Type respectively.
+
+## 5.0.1
+
+- Add a the xcode tools llvm as default path on MacOS.
+
+## 5.0.0
+
+- Stable release targeting Dart 2.17, supporting ABI-specific integer types.
+- _EXPERIMENTAL_ support for ObjectiveC on MacOS hosts. The API and output
+  might change at any point. Feel free to report bugs if encountered.
+
+## 5.0.0-dev.1
+- Fixed invalid default dart types being generated for `size_t` and `wchar_t`.
+

+## 4.0.0
+- Release for Dart SDK `>=2.14`.
+
+## 4.0.0-dev.2
+- Added config key `functions -> expose-typedefs` to expose the typedef
+to Native and Dart type.
+- Config key `function`->`symbol-address` no longer exposes the typedef
+to Native type. Use `expose-typedefs` to get the native type.
+
+## 4.0.0-dev.1
+- This package now targets package:lints for the generated code. The generated
+code uses C symbol names as is. Use either `// ignore_for_file: lintRule1, lintRule2`
+in the `preamble`, or rename the symbols to make package:lints happy.
+- Name collisions are now resolved by suffixing `<int>` instead of `_<int>`.
+
+## 4.0.0-dev.0
+- Added support for generating typedefs (_referred_ typedefs only).
+<table>
+<tr>
+<td>Example C Code</td>
+<td>Generated Dart typedef</td>
+</tr>
+<tr>
+<td>
+
+```C++
+typedef struct A{
+    ...
+} TA, *PA;

+typedef TA = A;
+typedef PA = ffi.Pointer<A>;
+TA func(PA ptr){...}
+```
+</td>
+</tr>
+</table>
+
+- All declarations that are excluded by the user are now only included if being
+used somewhere.

+typedef that refers to them.
+
+## 3.1.0-dev.1

+automatically but can be overriden using `structs -> pack` config.
+- Updated sdk constraints to `>=2.13.0-211.6.beta`.
+
+## 2.4.2
+- Fix issues due to declarations having duplicate names.
+- Fix name conflict of declaration with ffi library prefix.

+structs having `Opaque` members.
+
+## 2.0.1

+
+Binding generator for [FFI](https://dart.dev/guides/libraries/c-interop) bindings.
+
+> Note: ffigen only supports parsing `C` headers, not `C++` headers.
+
+This bindings generator can be used to call C code -- or code in another
+language that compiles to C modules that follow the C calling convention --
+such as Go or Rust. For more details, see:
+https://dart.dev/guides/libraries/c-interop
+
+ffigen also has experimental support for calling ObjC and Swift code;
+for details see:
+https://dart.dev/guides/libraries/objective-c-interop
+
+## Example
+
+For some header file _example.h_:
+```C
+int sum(int a, int b);
+```
+Add configurations to Pubspec File:
+```yaml
+ffigen:
+  output: 'generated_bindings.dart'
+  headers:
+    entry-points:
+      - 'example.h'
+```
+Output (_generated_bindings.dart_).
+```dart
+import 'dart:ffi' as ffi;
+class NativeLibrary {
+  final ffi.Pointer<T> Function<T extends ffi.NativeType>(String symbolName)
+      _lookup;
+  NativeLibrary(ffi.DynamicLibrary dynamicLibrary)
+      : _lookup = dynamicLibrary.lookup;
+  NativeLibrary.fromLookup(
+      ffi.Pointer<T> Function<T extends ffi.NativeType>(String symbolName)
+          lookup)
+      : _lookup = lookup;
+
+  int sum(int a, int b) {
+    return _sum(a, b);
+  }
+
+  late final _sumPtr = _lookup<ffi.NativeFunction<ffi.Int Function(ffi.Int, ffi.Int)>>('sum');
+  late final _sum = _sumPtr.asFunction<int Function(int, int)>();
+}
+}
+```
+## Using this package
+- Add `ffigen` under `dev_dependencies` in your `pubspec.yaml` (run `dart pub add -d ffigen`).
+- Add `package:ffi` under `dependencies` in your `pubspec.yaml` (run `dart pub add ffi`).
+- Install LLVM (see [Installing LLVM](#installing-llvm)).
+- Configurations must be provided in `pubspec.yaml` or in a custom YAML file (see [configurations](#configurations)).
+- Run the tool- `dart run ffigen`.
+
+Jump to [FAQ](#faq).
+
+## Installing LLVM
+`package:ffigen` uses LLVM. Install LLVM (9+) in the following way.
+
+#### Linux
+1. Install libclangdev.
+
+   With apt-get: `sudo apt-get install libclang-dev`.
+
+   With dnf: `sudo dnf install clang-devel`.
+
+#### Windows
+1. Install Visual Studio with C++ development support.
+2. Install [LLVM](https://releases.llvm.org/download.html) or `winget install -e --id LLVM.LLVM`.
+
+#### MacOS
+1. Install Xcode.
+2. Install Xcode command line tools - `xcode-select --install`.
+3. Install LLVM - `brew install llvm`.
+
+## Configurations
+Configurations can be provided in 2 ways-
+1. In the project's `pubspec.yaml` file under the key `ffigen`.
+2. Via a custom YAML file, then specify this file while running -
+`dart run ffigen --config config.yaml`
+
+The following configuration options are available-

+## Trying out examples
+1. `cd examples/<example_u_want_to_run>`, Run `dart pub get`.
+2. Run `dart run ffigen`.
+
+## Running Tests
+
+See [test/README.md](test/README.md)
+
+## FAQ
+### Can ffigen be used for removing underscores or renaming declarations?
+Ffigen supports **regexp based renaming**, the regexp must be a
+full match, for renaming you can use regexp groups (`$1` means group 1).
+
+E.g - For renaming `clang_dispose_string` to `string_dispose`.
+We can can match it using `clang_(.*)_(.*)` and rename with `$2_$1`.
+
+Here's an example of how to remove prefix underscores from any struct and its members.
+```yaml
+structs:
+  ...
+  rename:
+    '_(.*)': '$1' # Removes prefix underscores from all structures.
+  member-rename:
+    '.*': # Matches any struct.
+      '_(.*)': '$1' # Removes prefix underscores from members.
+```
+### How to generate declarations only from particular headers?
+The default behaviour is to include everything directly/transitively under
+each of the `entry-points` specified.
+
+If you only want to have declarations directly particular header you can do so
+using `include-directives`. You can use **glob matching** to match header paths.
+```yaml
+headers:
+  entry-points:
+    - 'path/to/my_header.h'
+  include-directives:
+    - '**my_header.h' # This glob pattern matches the header path.
+```
+### Can ffigen filter declarations by name?
+Ffigen supports including/excluding declarations using full regexp matching.
+
+Here's an example to filter functions using names
+```yaml
+functions:
+  include:
+    - 'clang.*' # Include all functions starting with clang.
+  exclude:
+    - '.*dispose': # Exclude all functions ending with dispose.
+```
+This will include `clang_help`. But will exclude `clang_dispose`.
+
+Note: exclude overrides include.
+### How does ffigen handle C Strings?
+
+Ffigen treats `char*` just as any other pointer,(`Pointer<Int8>`).
+To convert these to/from `String`, you can use [package:ffi](https://pub.dev/packages/ffi). Use `ptr.cast<Utf8>().toDartString()` to convert `char*` to dart `string` and `"str".toNativeUtf8()` to convert `string` to `char*`.
+
+### How are unnamed enums handled?
+
+Unnamed enums are handled separately, under the key `unnamed-enums`, and are generated as top level constants.
+
+Here's an example that shows how to include/exclude/rename unnamed enums
+```yaml
+unnamed-enums:
+  include:
+    - 'CX_.*'
+  exclude:
+    - '.*Flag'
+  rename:
+    'CXType_(.*)': '$1'
+```
+
+### Why are some struct/union declarations generated even after excluded them in config?
+
+This happens when an excluded struct/union is a dependency to some included declaration.
+(A dependency means a struct is being passed/returned by a function or is member of another struct in some way)
+
+Note: If you supply `structs` -> `dependency-only` as `opaque` ffigen will generate
+these struct dependencies as `Opaque` if they were only passed by reference(pointer).
+```yaml
+structs:
+  dependency-only: opaque
+unions:
+  dependency-only: opaque
+```
+
+### How to expose the native pointers?
+
+By default the native pointers are private, but you can use the
+`symbol-address` subkey for functions/globals and make them public by matching with its name. The pointers are then accesible via `nativeLibrary.addresses`.
+
+Example -
+```yaml
+functions:
+  symbol-address:
+    include:
+      - 'myFunc' # Match function name.
+      - '.*' # Do this to expose all function pointers.
+    exclude: # If you only use exclude, then everything not excluded is generated.
+      - 'dispose'
+```
+
+### How to get typedefs to Native and Dart type of a function?
+
+By default these types are inline. But you can use the `expose-typedef` subkey
+for functions to generate them. This will expose the Native and Dart type.
+E.g - for a function named `hello`, the generated typedefs are named
+as `NativeHello` and `DartHello`.
+
+Example -
+```yaml
+functions:
+  expose-typedefs:
+    include:
+      - 'myFunc' # Match function name.
+      - '.*' # Do this to expose types for all function.
+    exclude: # If you only use exclude, then everything not excluded is generated.
+      - 'dispose'
+```
+
+### How are Structs/Unions/Enums that are reffered to via typedefs handled?
+
+Named declarations use their own names even when inside another typedef.
+However, unnamed declarations inside typedefs take the name of the _first_ typedef
+that refers to them.
+
+### Why are some typedefs not generated?
+
+The following typedefs are not generated -
+  - They are not referred to anywhere in the included declarations.
+  - They refer to a struct/union having the same name as itself.
+  - They refer to a boolean, enum, inline array, Handle or any unsupported type.
+
+### How are macros handled?
+
+`ffigen` uses `clang`'s own compiler frontend to parse and traverse the `C` header files. `ffigen` expands the macros using `clang`'s macro expansion and then traverses the expanded code. To do this, `ffigen` generates temporary files in a system tmp directory.
+
+A custom temporary directory can be specified by setting the `TEST_TMPDIR` environment variable.
+
+### What are these logs generated by ffigen and how to fix them?
+
+Ffigen can sometimes generate a lot of logs, especially when it's parsing a lot of code.
+  - `SEVERE` logs are something you *definitely need to address*. They can be
+    caused due to syntax errors, or more generally missing header files
+    (which need to be specified using `compiler-opts` in config)
+  - `WARNING` logs are something *you can ignore*, but should probably look into.
+    These are mostly indications of declarations ffigen couldn't generate due
+    to limitations of dart:ffi, private declarations (which can be resolved
+    by renaming them via ffigen config) or other minor issues in the config
+    file itself.
+  - Everything else can be safely ignored. It's purpose is to simply
+    let you know what ffigen is doing.
+  - The verbosity of the logs can be changed by adding a flag with
+    the log level. E.g - `dart run ffigen --verbose <level>`.
+    Level options are - `[all, fine, info (default), warning, severe]`.
+    The `all` and `fine` will print a ton of logs are meant for debugging
+    purposes only.
+
+### How can type definitions be shared?
+
+Ffigen can share type definitions using symbol files.
+- A package can generate a symbol file using the `output -> symbol-file` config.
+- And another package can then import this, using `import -> symbol-files` config.
+- Doing so will reuse all the types such as Struct/Unions, and will automatically
+ exclude generating other types (E.g functions, enums, macros).
+
+Checkout `examples/shared_bindings` for details.
+
+For manually reusing definitions from another package, the `library-imports`
+and `type-map` config can be used.

+# Natives example
+
+A simple example generating `Native` bindings for a very small header file (`headers/example.h`).
+
+## Generating bindings
+At the root of this example (`example/simple`), run -
+```
+dart run ffigen --config config.yaml
+```
+This will generate bindings in a file: [generated_bindings.dart](./generated_bindings.dart).

+## Config notes
+
+The ffigen config for an Objective C library looks very similar to a C library.
+The most important difference is that you must set `language: objc`. If you want
+to filter which interfaces are included you can use the `objc-interfaces:`
+option. This works similarly to the other filtering options.
+
+It is recommended that you filter out just about everything you're not
+interested in binding (see the ffigen config in [pubspec.yaml](./pubspec.yaml)).
+Virtually all Objective C libraries depend on Apple's internal libraries, which
+are huge. Filtering can reduce the generated bindings from millions of lines to
+tens of thousands. You can use the `exclude-all-by-default` flag, or exclude
+individual sets of declarations like this:
+
+```yaml
+functions:
+  exclude:
+    - '.*'
+# Same for structs/unions/enums etc.
+```
+
+In this example, we're only interested in `AVAudioPlayer`, so we've filtered out
+everything else. But ffigen will automatically pull in anything referenced by
+any of the fields or methods of `AVAudioPlayer`, so we're still able to use
+`NSURL` etc to load our audio file.
+
+## Generating bindings
+
+At the root of this example (`example/objective_c`), run:
+
+```
+dart run ffigen --config config.yaml
+```
+
+This will generate [avf_audio_bindings.dart](./avf_audio_bindings.dart).

+# Swift example
+
+This example shows how to use ffigen to interact with Swift libraries.
+
+Swift APIs can be made compatible with Objective-C, using the `@objc`
+annotation. Then you can use the `swiftc` tool to build a dylib for the library
+using `-emit-library`, and generate an Objective-C wrapper header using
+`-emit-objc-header-path filename.h`:
+
+```shell
+swiftc -c swift_api.swift                           \
+    -module-name swift_module                       \
+    -emit-objc-header-path third_party/swift_api.h  \
+    -emit-library -o libswiftapi.dylib
+```
+
+This should generate libswiftapi.dylib and swift_api.h.
+For more information about Objective-C / Swift interoperability, see the
+[Apple documentation](https://developer.apple.com/documentation/swift/importing-swift-into-objective-c).
+
+Once you have an Objective-C wrapper header, ffigen can parse it like
+any other header:
+
+```shell
+dart run ffigen --config config.yaml
+```
+
+This will generate [swift_api_bindings.dart](./swift_api_bindings.dart),
+using the config in the ffigen section of the pubspec.yaml.
+
+Finally, you can run the example using this command:
+
+```shell
+dart run example.dart
+```
+
+## Config notes
+
+Ffigen only sees the Objective-C wrapper header, swift_api.h. So you
+need to set the language to objc, and set the entry-point to the header:
+
+```yaml
+language: objc
+headers:
+  entry-points:
+    - 'third_party/swift_api.h'
+```
+
+Swift classes become Objective-C interfaces, so include them like this:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+```
+
+There is one extra option you need to set when wrapping a Swift library.
+When `swiftc` compiles the library, it gives the Objective-C interface
+a module prefix. Internally, our `SwiftClass` is actually registered
+as `swift_module.SwiftClass`. So you need to tell ffigen about this prefix,
+so it loads the correct class from the dylib:
+
+```yaml
+objc-interfaces:
+  include:
+    - 'SwiftClass'
+  module:
+    'SwiftClass': 'swift_module'
+```
+
+The module prefix is whatever you passed to `swiftc` in the
+`-module-name` flag.

+# Overview
+`package:ffigen` simplifies the process of generating `dart:ffi` bindings from C header files. It is simple to use, with the input being a small YAML config file. It requires LLVM (9+) to work. This document tries to give a complete overview of every component without going into too many details about every single class/file.
+# LibClang
+`package:ffigen` binds to LibClang using `dart:ffi` for parsing C header files. 
+## Bindings
+The config file for generating bindings is `tool/libclang_config.yaml`. The bindings are generated to `lib/src/header_parser/clang_bindings/clang_bindings.dart`. These are used by [Header Parser](#header-parser) for calling libclang functions.
+# Scripts
+## ffigen.dart
+This is the main entry point for the user-  `dart run ffigen`.
+- Command-line options:
+    - `--verbose`: Sets log level.
+    - `--config`: Specifies a config file.
+- The internal modules are called by `ffigen.dart` in the following way:
+- `ffigen.dart` will try to find dynamic library in default locations. If that fails, the user must excplicitly specify location in ffigen's config under the key `llvm-path`.
+    - It first creates a `Config` object from an input Yaml file. This is used by other modules.
+    - The `parse` method is then invoked to generate a `Library` object.
+    - Finally, the code is generated from the `Library` object to the specified file.
+# Components
+## Config Provider
+The Config Provider holds all the configurations required by other modules.
+- Config Provider handles validation and extraction of configurations from YAML files.
+- Config Provider converts configurations to the format required by other modules. This object is passed around to every other module.
+## Header Parser
+The Header Parser parses C header files and converts them into a `Library` object.
+- Header Parser handles including/excluding/renaming of declarations.
+- Header Parser also filters out any _unimplemented_ or _unsupported_ declarations before generating a `Library` object.
+## Code Generator
+The Code Generator generates the actual string bindings.
+- Code generator handles all external name collisions, while internal name conflicts are handled by each specific `Binding`.
+- Code Generator also handles how workarounds for arrays and bools are generated.

+
+## Running Tests
+
+1.  Some tests require that dynamic libraries be built before running the tests.
+    You can do so with:
+
+    ```shell
+    dart run test/setup.dart
+    ```
+
+2.  Run the tests with:
+
+    ```shell
+    dart test
+    ```
+
+## Development
+
+Some tests verify that the generated Dart FFI bindings match a golden file.
+
+For example, the test
+[`test/native_test/native_test.dart`](https://github.com/dart-lang/native/tree/main/pkgs/ffigen/test/native_test/native_test.dart)
+works by:
+
+1.  Loading the dynamic library for
+    [`test/native_test/native_test.c`](https://github.com/dart-lang/native/tree/main/pkgs/ffigen/test/native_test/native_test.c)
+    (which was generated by `dart run test/setup.dart`).
+
+2.  Generating binding files for that dynamic library in the
+    `test/debug_generated` directory.
+
+3.  Comparing the golden file (i.e.
+    [`test/native_test/_expected_native_test_bindings.dart`](https://github.com/dart-lang/native/tree/main/pkgs/ffigen/test/native_test/_expected_native_test_bindings.dart))
+    to the generated file and generating a test failure if they do not match.
+
+4.  Using the *golden* bindings to excercise the dynamic library.
+
+If you modify any source for a dynamic library (e.g. any `.c`, `.h` or `.m`
+files), then you should run:
+
+```shell
+   dart run test/setup.dart  # Rebuild the dynamic libraries.
+   dart run test/regen.dart  # Rebuild the golden FFI bindings.
+```
+
+If you modify any code that changes how FFI bindings are generated, then you
+should run:
+
+  ```shell
+  dart run test/regen.dart  # Rebuild the golden FFI bindings.
+  ```
+
+A conservative way to run tests is with:
+
+  ```shell
+  dart run test/setup.dart && dart run test/regen.dart && dart test
+  ```
+
+> Note: you should verify that the changes to the golden bindings are
+> reasonable with `git diff`.

+  /// the mode parameter that is less restrictive than that specified by
+  /// the flags passed in the third parameter to sqlite3_open_v2().
+  ///
+  /// <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+  /// "private". ^Setting it to "shared" is equivalent to setting the

+  /// ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+  /// a URI filename, its value overrides any behavior requested by setting
+  /// SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+  ///
+  /// <li> <b>psow</b>: ^The psow parameter indicates whether or not the
+  /// [powersafe overwrite] property does or does not apply to the
+  /// storage media on which the database file resides.
+  ///
+  /// <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter

+  /// support locking.  Caution:  Database corruption might result if two
+  /// or more processes write to the same database and any one of those
+  /// processes uses nolock=1.
+  ///
+  /// <li> <b>immutable</b>: ^The immutable parameter is a boolean query
+  /// parameter that indicates that the database file is stored on

+  /// These routines extract type, size, and content information from
+  /// [protected sqlite3_value] objects.  Protected sqlite3_value objects
+  /// are used to pass parameter information into the functions that
+  /// implement [application-defined SQL functions] and [virtual tables].
+  ///
+  /// These routines work only with [protected sqlite3_value] objects.
+  /// Any attempt to use these routines on an [unprotected sqlite3_value]
+  /// is not threadsafe.
+  ///
+  /// ^These routines work just like the corresponding [column access functions]
+  /// except that these routines take a single [protected sqlite3_value] object
+  /// pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
+  ///
+  /// ^The sqlite3_value_text16() interface extracts a UTF-16 string
+  /// in the native byte-order of the host machine.  ^The
+  /// sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+  /// extract UTF-16 strings as big-endian and little-endian respectively.
+  ///
+  /// ^If [sqlite3_value] object V was initialized
+  /// using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
+  /// and if X and Y are strings that compare equal according to strcmp(X,Y),
+  /// then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
+  /// sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer()
+  /// routine is part of the [pointer passing interface] added for SQLite 3.20.0.
+  ///
+  /// ^(The sqlite3_value_type(V) interface returns the
+  /// [SQLITE_INTEGER | datatype code] for the initial datatype of the
+  /// [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
+  /// [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
+  /// Other interfaces might change the datatype for an sqlite3_value object.
+  /// For example, if the datatype is initially SQLITE_INTEGER and
+  /// sqlite3_value_text(V) is called to extract a text value for that
+  /// integer, then subsequent calls to sqlite3_value_type(V) might return
+  /// SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
+  /// occurs is undefined and may change from one release of SQLite to the next.
+  ///
+  /// ^(The sqlite3_value_numeric_type() interface attempts to apply
+  /// numeric affinity to the value.  This means that an attempt is
+  /// made to convert the value to an integer or floating point.  If
+  /// such a conversion is possible without loss of information (in other
+  /// words, if the value is a string that looks like a number)
+  /// then the conversion is performed.  Otherwise no conversion occurs.

+  ///
+  /// ^Within the [xUpdate] method of a [virtual table], the

+  /// that the xUpdate method call was invoked to implement and if

+  /// the value for that column returned without setting a result (probably
+  /// because it queried [sqlite3_vtab_nochange()] and found that the column
+  /// was unchanging).  ^Within an [xUpdate] method, any value for which
+  /// sqlite3_value_nochange(X) is true will in all other respects appear
+  /// to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
+  /// than within an [xUpdate] method call for an UPDATE statement, then
+  /// the return value is arbitrary and meaningless.
+  ///
+  /// ^The sqlite3_value_frombind(X) interface returns non-zero if the
+  /// value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
+  /// interfaces.  ^If X comes from an SQL literal value, or a table column,
+  /// or an expression, then sqlite3_value_frombind(X) returns zero.
+  ///
+  /// Please pay particular attention to the fact that the pointer returned
+  /// from [sqlite3_value_blob()], [sqlite3_value_text()], or

+  /// However, the signature of the callback function allows SQLite to pass
+  /// it an array of void* context pointers. The first argument passed to
+  /// an unlock-notify callback is a pointer to an array of void* pointers,
+  /// and the second is the number of entries in the array.
+  ///
+  /// When a blocking connection's transaction is concluded, there may be
+  /// more than one blocked connection that has registered for an unlock-notify
+  /// callback. ^If two or more such blocked connections have specified the
+  /// same callback function, then instead of invoking the callback function
+  /// multiple times, it is invoked once with the set of void* context pointers
+  /// specified by the blocked connections bundled together into an array.
+  /// This gives the application an opportunity to prioritize any actions
+  /// related to the set of unblocked database connections.
+  ///
+  /// <b>Deadlock Detection</b>
+  ///
+  /// Assuming that after registering for an unlock-notify callback a
+  /// database waits for the callback to be issued before taking any further
+  /// action (a reasonable assumption), then using this API may cause the
+  /// application to deadlock. For example, if connection X is waiting for
+  /// connection Y's transaction to be concluded, and similarly connection
+  /// Y is waiting on connection X's transaction, then neither connection
+  /// will proceed and the system may remain deadlocked indefinitely.
+  ///
+  /// To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+  /// detection. ^If a given call to sqlite3_unlock_notify() would put the
+  /// system in a deadlocked state, then SQLITE_LOCKED is returned and no
+  /// unlock-notify callback is registered. The system is said to be in
+  /// a deadlocked state if connection A has registered for an unlock-notify
+  /// callback on the conclusion of connection B's transaction, and connection
+  /// B has itself registered for an unlock-notify callback when connection
+  /// A's transaction is concluded. ^Indirect deadlock is also detected, so
+  /// the system is also considered to be deadlocked if connection B has
+  /// registered for an unlock-notify callback on the conclusion of connection
+  /// C's transaction, where connection C is waiting on connection A. ^Any
+  /// number of levels of indirection are allowed.
+  ///
+  /// <b>The "DROP TABLE" Exception</b>
+  ///
+  /// When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
+  /// always appropriate to call sqlite3_unlock_notify(). There is however,
+  /// one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,

+/// CAPI3REF: Virtual Table Indexing Information
+/// KEYWORDS: sqlite3_index_info
+///
+/// The sqlite3_index_info structure and its substructures is used as part
+/// of the [virtual table] interface to
+/// pass information into and receive the reply from the [xBestIndex]
+/// method of a [virtual table module].  The fields under **Inputs** are the
+/// inputs to xBestIndex and are read-only.  xBestIndex inserts its
+/// results into the **Outputs** fields.
+///
+/// ^(The aConstraint[] array records WHERE clause constraints of the form:
+///
+/// <blockquote>column OP expr</blockquote>
+///
+/// where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
+/// stored in aConstraint[].op using one of the
+/// [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
+/// ^(The index of the column is stored in
+/// aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
+/// expr on the right-hand side can be evaluated (and thus the constraint
+/// is usable) and false if it cannot.)^
+///
+/// ^The optimizer automatically inverts terms of the form "expr OP column"
+/// and makes other simplifications to the WHERE clause in an attempt to
+/// get as many WHERE clause terms into the form shown above as possible.
+/// ^The aConstraint[] array only reports WHERE clause terms that are
+/// relevant to the particular virtual table being queried.
+///
+/// ^Information about the ORDER BY clause is stored in aOrderBy[].
+/// ^Each term of aOrderBy records a column of the ORDER BY clause.
+///
+/// The colUsed field indicates which columns of the virtual table may be
+/// required by the current scan. Virtual table columns are numbered from
+/// zero in the order in which they appear within the CREATE TABLE statement
+/// passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
+/// the corresponding bit is set within the colUsed mask if the column may be
+/// required by SQLite. If the table has at least 64 columns and any column
+/// to the right of the first 63 is required, then bit 63 of colUsed is also
+/// set. In other words, column iCol may be required if the expression
+/// (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
+/// non-zero.
+///
+/// The [xBestIndex] method must fill aConstraintUsage[] with information
+/// about what parameters to pass to xFilter.  ^If argvIndex>0 then
+/// the right-hand side of the corresponding aConstraint[] is evaluated
+/// and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
+/// is true, then the constraint is assumed to be fully handled by the
+/// virtual table and might not be checked again by the byte code.)^ ^(The
+/// aConstraintUsage[].omit flag is an optimization hint. When the omit flag
+/// is left in its default setting of false, the constraint will always be
+/// checked separately in byte code.  If the omit flag is change to true, then
+/// the constraint may or may not be checked in byte code.  In other words,
+/// when the omit flag is true there is no guarantee that the constraint will
+/// not be checked again using byte code.)^
+///
+/// ^The idxNum and idxPtr values are recorded and passed into the
+/// [xFilter] method.
+/// ^[sqlite3_free()] is used to free idxPtr if and only if
+/// needToFreeIdxPtr is true.
+///
+/// ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
+/// the correct order to satisfy the ORDER BY clause so that no separate
+/// sorting step is required.
+///
+/// ^The estimatedCost value is an estimate of the cost of a particular
+/// strategy. A cost of N indicates that the cost of the strategy is similar
+/// to a linear scan of an SQLite table with N rows. A cost of log(N)
+/// indicates that the expense of the operation is similar to that of a
+/// binary search on a unique indexed field of an SQLite table with N rows.
+///
+/// ^The estimatedRows value is an estimate of the number of rows that
+/// will be returned by the strategy.
+///
+/// The xBestIndex method may optionally populate the idxFlags field with a
+/// mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+/// SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+/// assumes that the strategy may visit at most one row.
+///
+/// Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+/// SQLite also assumes that if a call to the xUpdate() method is made as
+/// part of the same statement to delete or update a virtual table row and the
+/// implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+/// any database changes. In other words, if the xUpdate() returns
+/// SQLITE_CONSTRAINT, the database contents must be exactly as they were
+/// before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+/// set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+/// the xUpdate method are automatically rolled back by SQLite.
+///
+/// IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
+/// structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
+/// If a virtual table extension is
+/// used with an SQLite version earlier than 3.8.2, the results of attempting
+/// to read or write the estimatedRows field are undefined (but are likely
+/// to include crashing the application). The estimatedRows field should
+/// therefore only be used if [sqlite3_libversion_number()] returns a
+/// value greater than or equal to 3008002. Similarly, the idxFlags field
+/// was added for [version 3.9.0] ([dateof:3.9.0]).
+/// It may therefore only be used if
+/// sqlite3_libversion_number() returns a value greater than or equal to
+/// 3009000.

+/// the third argument to pUserData.
+///
+/// If the callback function returns any value other than SQLITE_OK, the
+/// query is abandoned and the xQueryPhrase function returns immediately.
+/// If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+/// Otherwise, the error code is propagated upwards.
+///
+/// If the query runs to completion without incident, SQLITE_OK is returned.
+/// Or, if some error occurs before the query completes or is aborted by
+/// the callback, an SQLite error code is returned.
+///
+///
+/// xSetAuxdata(pFts5, pAux, xDelete)
+///
+/// Save the pointer passed as the second argument as the extension function's
+/// "auxiliary data". The pointer may then be retrieved by the current or any
+/// future invocation of the same fts5 extension function made as part of
+/// the same MATCH query using the xGetAuxdata() API.
+///
+/// Each extension function is allocated a single auxiliary data slot for
+/// each FTS query (MATCH expression). If the extension function is invoked
+/// more than once for a single FTS query, then all invocations share a
+/// single auxiliary data context.
+///
+/// If there is already an auxiliary data pointer when this function is
+/// invoked, then it is replaced by the new pointer. If an xDelete callback
+/// was specified along with the original pointer, it is invoked at this
+/// point.
+///
+/// The xDelete callback, if one is specified, is also invoked on the
+/// auxiliary data pointer after the FTS5 query has finished.
+///
+/// If an error (e.g. an OOM condition) occurs within this function,
+/// the auxiliary data is set to NULL and an error code returned. If the
+/// xDelete parameter was not NULL, it is invoked on the auxiliary data
+/// pointer before returning.
+///
+///
+/// xGetAuxdata(pFts5, bClear)
+///
+/// Returns the current auxiliary data pointer for the fts5 extension
+/// function. See the xSetAuxdata() method for details.
+///
+/// If the bClear argument is non-zero, then the auxiliary data is cleared
+/// (set to NULL) before this function returns. In this case the xDelete,
+/// if any, is not invoked.
+///
+///
+/// xRowCount(pFts5, pnRow)
+///
+/// This function is used to retrieve the total number of rows in the table.
+/// In other words, the same value that would be returned by:
+///
+/// SELECT count(*) FROM ftstable;
+///
+/// xPhraseFirst()
+/// This function is used, along with type Fts5PhraseIter and the xPhraseNext
+/// method, to iterate through all instances of a single query phrase within
+/// the current row. This is the same information as is accessible via the
+/// xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+/// to use, this API may be faster under some circumstances. To iterate
+/// through instances of phrase iPhrase, use the following code:
+///
+/// Fts5PhraseIter iter;
+/// int iCol, iOff;
+/// for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+/// iCol>=0;
+/// pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+/// ){
+/// // An instance of phrase iPhrase at offset iOff of column iCol
+/// }
+///
+/// The Fts5PhraseIter structure is defined above. Applications should not
+/// modify this structure directly - it should only be used as shown above
+/// with the xPhraseFirst() and xPhraseNext() API methods (and by
+/// xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" or "detail=column" option. If the FTS5 table is created
+/// with either "detail=none" or "detail=column" and "content=" option
+/// (i.e. if it is a contentless table), then this API always iterates
+/// through an empty set (all calls to xPhraseFirst() set iCol to -1).
+///
+/// xPhraseNext()
+/// See xPhraseFirst above.
+///
+/// xPhraseFirstColumn()
+/// This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+/// and xPhraseNext() APIs described above. The difference is that instead
+/// of iterating through all instances of a phrase in the current row, these
+/// APIs are used to iterate through the set of columns in the current row
+/// that contain one or more instances of a specified phrase. For example:
+///
+/// Fts5PhraseIter iter;
+/// int iCol;
+/// for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+/// iCol>=0;
+/// pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+/// ){
+/// // Column iCol contains at least one instance of phrase iPhrase
+/// }
+///
+/// This API can be quite slow if used with an FTS5 table created with the
+/// "detail=none" option. If the FTS5 table is created with either
+/// "detail=none" "content=" option (i.e. if it is a contentless table),
+/// then this API always iterates through an empty set (all calls to
+/// xPhraseFirstColumn() set iCol to -1).
+///
+/// The information accessed using this API and its companion
+/// xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+/// (or xInst/xInstCount). The chief advantage of this API is that it is
+/// significantly more efficient than those alternatives when used with
+/// "detail=column" tables.
+///
+/// xPhraseNextColumn()
+/// See xPhraseFirstColumn above.

+ *
+ * In both Objective-C and C++, a method (aka virtual member function,

+ * Objective-C, a method is said to override any method in the class's
+ * base class, its protocols, or its categories' protocols, that has the same
+ * selector and is of the same kind (class or instance).
+ * If no such method exists, the search continues to the class's superclass,

+ * implementation is considered to override the same methods as its
+ * corresponding method in the interface.
+ *
+ * For C++, a virtual member function overrides any virtual member
+ * function with the same signature that occurs in its base
+ * classes. With multiple inheritance, a virtual member function can
+ * override several virtual member functions coming from different
+ * base classes.
+ *
+ * In all cases, this function determines the immediate overridden
+ * method, rather than all of the overridden methods. For example, if
+ * a method is originally declared in a class A, then overridden in B
+ * (which in inherits from A) and also in C (which inherited from B),
+ * then the only overridden method returned from this function when
+ * invoked on C's method will be B's method. The client may then
+ * invoke this function again, given the previously-found overridden
+ * methods, to map out the complete method-override set.
+ *
+ * \param cursor A cursor representing an Objective-C or C++

+ * for code completion is that Clang will parse a complete source file,
+ * performing syntax checking up to the location where code-completion has
+ * been requested. At that point, a special code-completion token is passed
+ * to the parser, which recognizes this token and determines, based on the
+ * current location in the C/Objective-C/C++ grammar and the state of
+ * semantic analysis, what completions to provide. These completions are
+ * returned via a new \c CXCodeCompleteResults structure.
+ *
+ * Code completion itself is meant to be triggered by the client when the
+ * user types punctuation characters or whitespace, at which point the
+ * code-completion location will coincide with the cursor. For example, if \c p
+ * is a pointer, code-completion might be triggered after the "-" and then
+ * after the ">" in \c p->. When the code-completion location is after the ">",
+ * the completion results will provide, e.g., the members of the struct that
+ * "p" points to. The client is responsible for placing the cursor at the
+ * beginning of the token currently being typed, then filtering the results
+ * based on the contents of the token. For example, when code-completing for
+ * the expression \c p->get, the client should provide the location just after
+ * the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
+ * client can filter the results based on the current token text ("get"), only
+ * showing those results that start with "get". The intent of this interface
+ * is to separate the relatively high-latency acquisition of code-completion
+ * results from the filtering of results on a per-character basis, which must

+** that allows an application to run multiple statements of SQL
+** without having to use a lot of C code.

+** argument.  ^If the callback function of the 3rd argument to

+** coming out of the evaluated SQL statements.  ^The 4th argument to
+** sqlite3_exec() is relayed through to the 1st argument of each
+** callback invocation.  ^If the callback pointer to sqlite3_exec()
+** is NULL, then no callback is ever invoked and result rows are
+** ignored.
+**
+** ^If an error occurs while evaluating the SQL statements passed into
+** sqlite3_exec(), then execution of the current statement stops and
+** subsequent statements are skipped.  ^If the 5th parameter to sqlite3_exec()
+** is not NULL then any error message is written into memory obtained
+** from [sqlite3_malloc()] and passed back through the 5th parameter.
+** To avoid memory leaks, the application should invoke [sqlite3_free()]
+** on error message strings returned through the 5th parameter of
+** sqlite3_exec() after the error message string is no longer needed.
+** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
+** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
+** NULL before returning.
+**
+** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
+** routine returns SQLITE_ABORT without invoking the callback again and
+** without running any subsequent SQL statements.
+**
+** ^The 2nd argument to the sqlite3_exec() callback function is the
+** number of columns in the result.  ^The 3rd argument to the sqlite3_exec()
+** callback is an array of pointers to strings obtained as if from
+** [sqlite3_column_text()], one for each column.  ^If an element of a
+** result row is NULL then the corresponding string pointer for the
+** sqlite3_exec() callback is a NULL pointer.  ^The 4th argument to the
+** sqlite3_exec() callback is an array of pointers to strings where each
+** entry represents the name of corresponding result column as obtained

+** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
+** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
+** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
+** to NULL.
+**
+** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
+** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
+** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
+** flag may be ORed in to indicate that only the data of the file
+** and not its inode needs to be synced.

+** <li> [SQLITE_LOCK_NONE],

+** <li> [SQLITE_LOCK_RESERVED],
+** <li> [SQLITE_LOCK_PENDING], or
+** <li> [SQLITE_LOCK_EXCLUSIVE].
+** </ul>
+** xLock() increases the lock. xUnlock() decreases the lock.
+** The xCheckReservedLock() method checks whether any database connection,
+** either in this process or in some other process, is holding a RESERVED,
+** PENDING, or EXCLUSIVE lock on the file.  It returns true
+** if such a lock exists and false otherwise.
+**
+** The xFileControl() method is a generic interface that allows custom
+** VFS implementations to directly control an open file using the
+** [sqlite3_file_control()] interface.  The second "op" argument is an
+** integer opcode.  The third argument is a generic pointer intended to
+** point to a structure that may contain arguments or space in which to
+** write return values.  Potential uses for xFileControl() might be
+** functions to enable blocking locks with timeouts, to change the
+** locking strategy (for example to use dot-file locks), to inquire
+** about the status of a lock, or to break stale locks.  The SQLite
+** core reserves all opcodes less than 100 for its own use.
+** A [file control opcodes | list of opcodes] less than 100 is available.
+** Applications that define a custom xFileControl method should use opcodes
+** greater than 100 to avoid conflicts.  VFS implementations should
+** return [SQLITE_NOTFOUND] for file control opcodes that they do not
+** recognize.
+**
+** The xSectorSize() method returns the sector size of the
+** device that underlies the file.  The sector size is the

+** opcode causes the xFileControl method to write the current state of
+** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
+** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
+** into an integer that the pArg argument points to. This capability
+** is used during testing and is only available when the SQLITE_TEST
+** compile-time option is used.
+**
+** <li>[[SQLITE_FCNTL_SIZE_HINT]]
+** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
+** layer a hint of how large the database file will grow to be during the
+** current transaction.  This hint is not guaranteed to be accurate but it
+** is often close.  The underlying VFS might choose to preallocate database
+** file space based on this hint in order to help writes to the database
+** file run faster.
+**
+** <li>[[SQLITE_FCNTL_SIZE_LIMIT]]
+** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
+** implements [sqlite3_deserialize()] to set an upper bound on the size
+** of the in-memory database.  The argument is a pointer to a [sqlite3_int64].
+** If the integer pointed to is negative, then it is filled in with the
+** current limit.  Otherwise the limit is set to the larger of the value
+** of the integer pointed to and the current database size.  The integer
+** pointed to is set to the new limit.
+**
+** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
+** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
+** extends and truncates the database file in chunks of a size specified
+** by the user. The fourth argument to [sqlite3_file_control()] should 
+** point to an integer (type int) containing the new chunk-size to use
+** for the nominated database. Allocating database file space in large
+** chunks (say 1MB at a time), may reduce file-system fragmentation and
+** improve performance on some systems.
+**
+** <li>[[SQLITE_FCNTL_FILE_POINTER]]
+** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with a particular database
+** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
+**
+** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
+** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
+** to the [sqlite3_file] object associated with the journal file (either
+** the [rollback journal] or the [write-ahead log]) for a particular database
+** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
+**
+** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
+** No longer in use.
+**
+** <li>[[SQLITE_FCNTL_SYNC]]
+** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
+** sent to the VFS immediately before the xSync method is invoked on a
+** database file descriptor. Or, if the xSync method is not invoked 
+** because the user has configured SQLite with 
+** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place 
+** of the xSync method. In most cases, the pointer argument passed with
+** this file-control is NULL. However, if the database file is being synced
+** as part of a multi-database commit, the argument points to a nul-terminated
+** string containing the transactions master-journal file name. VFSes that 
+** do not need this signal should silently ignore this opcode. Applications 
+** should not call [sqlite3_file_control()] with this opcode as doing so may 
+** disrupt the operation of the specialized VFSes that do require it.  
+**
+** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
+** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
+** and sent to the VFS after a transaction has been committed immediately
+** but before the database is unlocked. VFSes that do not need this signal
+** should silently ignore this opcode. Applications should not call
+** [sqlite3_file_control()] with this opcode as doing so may disrupt the 
+** operation of the specialized VFSes that do require it.  
+**
+** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
+** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
+** retry counts and intervals for certain disk I/O operations for the
+** windows [VFS] in order to provide robustness in the presence of
+** anti-virus programs.  By default, the windows VFS will retry file read,
+** file write, and file delete operations up to 10 times, with a delay
+** of 25 milliseconds before the first retry and with the delay increasing
+** by an additional 25 milliseconds with each subsequent retry.  This
+** opcode allows these two values (10 retries and 25 milliseconds of delay)
+** to be adjusted.  The values are changed for all database connections
+** within the same process.  The argument is a pointer to an array of two
+** integers where the first integer is the new retry count and the second
+** integer is the delay.  If either integer is negative, then the setting
+** is not changed but instead the prior value of that setting is written
+** into the array entry, allowing the current retry settings to be
+** interrogated.  The zDbName parameter is ignored.
+**
+** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
+** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
+** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
+** write ahead log ([WAL file]) and shared memory
+** files used for transaction control
+** are automatically deleted when the latest connection to the database
+** closes.  Setting persistent WAL mode causes those files to persist after
+** close.  Persisting the files is useful when other processes that do not
+** have write permission on the directory containing the database file want
+** to read the database file, as the WAL and shared memory files must exist
+** in order for the database to be readable.  The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
+** WAL mode.  If the integer is -1, then it is overwritten with the current
+** WAL persistence setting.
+**
+** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
+** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
+** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
+** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
+** xDeviceCharacteristics methods. The fourth parameter to
+** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
+** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
+** mode.  If the integer is -1, then it is overwritten with the current
+** zero-damage mode setting.
+**
+** <li>[[SQLITE_FCNTL_OVERWRITE]]
+** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
+** a write transaction to indicate that, unless it is rolled back for some
+** reason, the entire database file will be overwritten by the current 
+** transaction. This is used by VACUUM operations.
+**
+** <li>[[SQLITE_FCNTL_VFSNAME]]
+** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
+** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
+** final bottom-level VFS are written into memory obtained from 
+** [sqlite3_malloc()] and the result is stored in the char* variable
+** that the fourth parameter of [sqlite3_file_control()] points to.
+** The caller is responsible for freeing the memory when done.  As with
+** all file-control actions, there is no guarantee that this will actually
+** do anything.  Callers should initialize the char* variable to a NULL
+** pointer in case this file-control is not implemented.  This file-control
+** is intended for diagnostic use only.
+**
+** <li>[[SQLITE_FCNTL_VFS_POINTER]]
+** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
+** [VFSes] currently in use.  ^(The argument X in
+** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
+** of type "[sqlite3_vfs] **".  This opcodes will set *X
+** to a pointer to the top-level VFS.)^
+** ^When there are multiple VFS shims in the stack, this opcode finds the
+** upper-most shim only.
+**
+** <li>[[SQLITE_FCNTL_PRAGMA]]
+** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] 
+** file control is sent to the open [sqlite3_file] object corresponding
+** to the database file to which the pragma statement refers. ^The argument
+** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
+** pointers to strings (char**) in which the second element of the array
+** is the name of the pragma and the third element is the argument to the
+** pragma or NULL if the pragma has no argument.  ^The handler for an
+** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
+** of the char** argument point to a string obtained from [sqlite3_mprintf()]
+** or the equivalent and that string will become the result of the pragma or
+** the error message if the pragma fails. ^If the
+** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal 
+** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
+** file control returns [SQLITE_OK], then the parser assumes that the
+** VFS has handled the PRAGMA itself and the parser generates a no-op
+** prepared statement if result string is NULL, or that returns a copy
+** of the result string if the string is non-NULL.
+** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
+** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
+** that the VFS encountered an error while handling the [PRAGMA] and the
+** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
+** file control occurs at the beginning of pragma statement analysis and so
+** it is able to override built-in [PRAGMA] statements.
+**
+** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
+** ^The [SQLITE_FCNTL_BUSYHANDLER]
+** file-control may be invoked by SQLite on the database file handle
+** shortly after it is opened in order to provide a custom VFS with access
+** to the connection's busy-handler callback. The argument is of type (void**)
+** - an array of two (void *) values. The first (void *) actually points
+** to a function of type (int (*)(void *)). In order to invoke the connection's
+** busy-handler, this function should be invoked with the second (void *) in
+** the array as the only argument. If it returns non-zero, then the operation
+** should be retried. If it returns zero, the custom VFS should abandon the
+** current operation.
+**
+** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
+** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
+** to have SQLite generate a
+** temporary filename using the same algorithm that is followed to generate
+** temporary filenames for TEMP tables and other internal uses.  The
+** argument should be a char** which will be filled with the filename
+** written into memory obtained from [sqlite3_malloc()].  The caller should
+** invoke [sqlite3_free()] on the result to avoid a memory leak.
+**
+** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
+** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
+** maximum number of bytes that will be used for memory-mapped I/O.
+** The argument is a pointer to a value of type sqlite3_int64 that
+** is an advisory maximum number of bytes in the file to memory map.  The
+** pointer is overwritten with the old value.  The limit is not changed if
+** the value originally pointed to is negative, and so the current limit 
+** can be queried by passing in a pointer to a negative number.  This
+** file-control is used internally to implement [PRAGMA mmap_size].
+**
+** <li>[[SQLITE_FCNTL_TRACE]]
+** The [SQLITE_FCNTL_TRACE] file control provides advisory information
+** to the VFS about what the higher layers of the SQLite stack are doing.
+** This file control is used by some VFS activity tracing [shims].
+** The argument is a zero-terminated string.  Higher layers in the
+** SQLite stack may generate instances of this file control if
+** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
+**
+** <li>[[SQLITE_FCNTL_HAS_MOVED]]
+** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
+** pointer to an integer and it writes a boolean into that integer depending
+** on whether or not the file has been renamed, moved, or deleted since it
+** was first opened.
+**
+** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
+** underlying native file handle associated with a file handle.  This file
+** control interprets its argument as a pointer to a native file handle and
+** writes the resulting value there.
+**
+** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
+** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
+** opcode causes the xFileControl method to swap the file handle with the one
+** pointed to by the pArg argument.  This capability is used during testing
+** and only needs to be supported when SQLITE_TEST is defined.
+**
+** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
+** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
+** be advantageous to block on the next WAL lock if the lock is not immediately
+** available.  The WAL subsystem issues this signal during rare
+** circumstances in order to fix a problem with priority inversion.
+** Applications should <em>not</em> use this file-control.
+**
+** <li>[[SQLITE_FCNTL_ZIPVFS]]
+** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
+** VFS should return SQLITE_NOTFOUND for this opcode.
+**
+** <li>[[SQLITE_FCNTL_RBU]]
+** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
+** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
+** this opcode.  
+**
+** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
+** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
+** the file descriptor is placed in "batch write mode", which
+** means all subsequent write operations will be deferred and done
+** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
+** that do not support batch atomic writes will return SQLITE_NOTFOUND.
+** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
+** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
+** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
+** no VFS interface calls on the same [sqlite3_file] file descriptor
+** except for calls to the xWrite method and the xFileControl method
+** with [SQLITE_FCNTL_SIZE_HINT].
+**
+** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to 
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
+** This file control returns [SQLITE_OK] if and only if the writes were
+** all performed successfully and have been committed to persistent storage.
+** ^Regardless of whether or not it is successful, this file control takes
+** the file descriptor out of batch write mode so that all subsequent
+** write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
+** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
+** operations since the previous successful call to 
+** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
+** ^This file control takes the file descriptor out of batch write mode
+** so that all subsequent write operations are independent.
+** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
+** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
+**
+** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
+** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
+** to block for up to M milliseconds before failing when attempting to 
+** obtain a file lock using the xLock or xShmLock methods of the VFS. 
+** The parameter is a pointer to a 32-bit signed integer that contains
+** the value that M is to be set to. Before returning, the 32-bit signed
+** integer is overwritten with the previous value of M.
+**
+** <li>[[SQLITE_FCNTL_DATA_VERSION]]
+** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
+** a database file.  The argument is a pointer to a 32-bit unsigned integer.
+** The "data version" for the pager is written into the pointer.  The
+** "data version" changes whenever any change occurs to the corresponding
+** database file, either through SQL statements on the same database
+** connection or through transactions committed by separate database
+** connections possibly in other processes. The [sqlite3_total_changes()]
+** interface can be used to find if any database on the connection has changed,
+** but that interface responds to changes on TEMP as well as MAIN and does
+** not provide a mechanism to detect changes to MAIN only.  Also, the
+** [sqlite3_total_changes()] interface responds to internal changes only and
+** omits changes made by other database connections.  The
+** [PRAGMA data_version] command provides a mechanism to detect changes to
+** a single attached database that occur due to other database connections,
+** but omits changes implemented by the database connection on which it is
+** called.  This file control is the only mechanism to detect changes that
+** happen either internally or externally and that are associated with
+** a particular attached database.
+**
+** <li>[[SQLITE_FCNTL_CKPT_START]]
+** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
+** in wal mode before the client starts to copy pages from the wal
+** file to the database file.
+**
+** <li>[[SQLITE_FCNTL_CKPT_DONE]]
+** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
+** in wal mode after the client has finished copying pages from the wal
+** file to the database file, but before the *-shm file is updated to
+** record the fact that the pages have been checkpointed.

+** CAPI3REF: OS Interface Object
+**
+** An instance of the sqlite3_vfs object defines the interface between
+** the SQLite core and the underlying operating system.  The "vfs"
+** in the name of the object stands for "virtual file system".  See
+** the [VFS | VFS documentation] for further information.
+**
+** The VFS interface is sometimes extended by adding new methods onto
+** the end.  Each time such an extension occurs, the iVersion field
+** is incremented.  The iVersion value started out as 1 in
+** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
+** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
+** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
+** may be appended to the sqlite3_vfs object and the iVersion value
+** may increase again in future versions of SQLite.
+** Note that due to an oversight, the structure
+** of the sqlite3_vfs object changed in the transition from
+** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
+** and yet the iVersion field was not increased.
+**
+** The szOsFile field is the size of the subclassed [sqlite3_file]
+** structure used by this VFS.  mxPathname is the maximum length of
+** a pathname in this VFS.
+**
+** Registered sqlite3_vfs objects are kept on a linked list formed by
+** the pNext pointer.  The [sqlite3_vfs_register()]
+** and [sqlite3_vfs_unregister()] interfaces manage this list
+** in a thread-safe way.  The [sqlite3_vfs_find()] interface
+** searches the list.  Neither the application code nor the VFS
+** implementation should use the pNext pointer.
+**
+** The pNext field is the only field in the sqlite3_vfs
+** structure that SQLite will ever modify.  SQLite will only access
+** or modify this field while holding a particular static mutex.
+** The application should never modify anything within the sqlite3_vfs
+** object once the object has been registered.
+**
+** The zName field holds the name of the VFS module.  The name must
+** be unique across all VFS modules.
+**
+** [[sqlite3_vfs.xOpen]]
+** ^SQLite guarantees that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname() with an optional suffix added.
+** ^If a suffix is added to the zFilename parameter, it will
+** consist of a single "-" character followed by no more than
+** 11 alphanumeric and/or "-" characters.
+** ^SQLite further guarantees that
+** the string will be valid and unchanged until xClose() is
+** called. Because of the previous sentence,
+** the [sqlite3_file] can safely store a pointer to the
+** filename if it needs to remember the filename for some reason.
+** If the zFilename parameter to xOpen is a NULL pointer then xOpen
+** must invent its own temporary name for the file.  ^Whenever the 
+** xFilename parameter is NULL it will also be the case that the
+** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
+**
+** The flags argument to xOpen() includes all bits set in
+** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
+** or [sqlite3_open16()] is used, then flags includes at least
+** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. 
+** If xOpen() opens a file read-only then it sets *pOutFlags to
+** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
+**
+** ^(SQLite will also add one of the following flags to the xOpen()

+** The file I/O implementation can use the object type flags to
+** change the way it deals with files.  For example, an application
+** that does not care about crash recovery or rollback might make
+** the open of a journal file a no-op.  Writes to this journal would
+** also be no-ops, and any attempt to read the journal would return
+** SQLITE_IOERR.  Or the implementation might recognize that a database
+** file will be doing page-aligned sector reads and writes in a random
+** order and set up its I/O subsystem accordingly.
+**
+** SQLite might also add one of the following flags to the xOpen method:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
+** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
+** will be set for TEMP databases and their journals, transient
+** databases, and subjournals.
+**
+** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
+** with the [SQLITE_OPEN_CREATE] flag, which are both directly
+** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
+** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the 
+** SQLITE_OPEN_CREATE, is used to indicate that file should always
+** be created, and that it is an error if it already exists.
+** It is <i>not</i> used to indicate the file should be opened 
+** for exclusive access.
+**
+** ^At least szOsFile bytes of memory are allocated by SQLite
+** to hold the [sqlite3_file] structure passed as the third
+** argument to xOpen.  The xOpen method does not have to
+** allocate the structure; it should just fill it in.  Note that
+** the xOpen method must set the sqlite3_file.pMethods to either
+** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
+** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
+** element will be valid after xOpen returns regardless of the success
+** or failure of the xOpen call.
+**
+** [[sqlite3_vfs.xAccess]]
+** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
+** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
+** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
+** to test whether a file is at least readable.  The SQLITE_ACCESS_READ
+** flag is never actually used and is not implemented in the built-in
+** VFSes of SQLite.  The file is named by the second argument and can be a
+** directory. The xAccess method returns [SQLITE_OK] on success or some
+** non-zero error code if there is an I/O error or if the name of
+** the file given in the second argument is illegal.  If SQLITE_OK
+** is returned, then non-zero or zero is written into *pResOut to indicate
+** whether or not the file is accessible.  
+**
+** ^SQLite will always allocate at least mxPathname+1 bytes for the
+** output buffer xFullPathname.  The exact size of the output buffer
+** is also passed as a parameter to both  methods. If the output buffer
+** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
+** handled as a fatal error by SQLite, vfs implementations should endeavor
+** to prevent this by setting mxPathname to a sufficiently large value.
+**
+** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
+** interfaces are not strictly a part of the filesystem, but they are
+** included in the VFS structure for completeness.
+** The xRandomness() function attempts to return nBytes bytes
+** of good-quality randomness into zOut.  The return value is
+** the actual number of bytes of randomness obtained.
+** The xSleep() method causes the calling thread to sleep for at
+** least the number of microseconds given.  ^The xCurrentTime()
+** method returns a Julian Day Number for the current date and time as
+** a floating point value.
+** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
+** Day Number multiplied by 86400000 (the number of milliseconds in 
+** a 24-hour day).  
+** ^SQLite will use the xCurrentTimeInt64() method to get the current
+** date and time if that method is available (if iVersion is 2 or 
+** greater and the function pointer is not NULL) and will fall back
+** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
+**
+** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
+** are not used by the SQLite core.  These optional interfaces are provided
+** by some VFSes to facilitate testing of the VFS code. By overriding 
+** system calls with functions under its control, a test program can
+** simulate faults and error conditions that would otherwise be difficult
+** or impossible to induce.  The set of system calls that can be overridden
+** varies from one VFS to another, and from one version of the same VFS to the
+** next.  Applications that use these interfaces must be prepared for any
+** or all of these interfaces to be NULL or for their behavior to change
+** from one release to the next.  Applications must not attempt to access
+** any of these methods if the iVersion of the VFS is less than 3.

+** These routines are designed to aid in process initialization and

+**
+** A call to sqlite3_initialize() is an "effective" call if it is

+** the process, or if it is the first time sqlite3_initialize() is invoked
+** following a call to sqlite3_shutdown().  ^(Only an effective call
+** of sqlite3_initialize() does any initialization.  All other calls

+** call to sqlite3_shutdown() since the last sqlite3_initialize().  ^(Only

+** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
+**
+** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
+** is not.  The sqlite3_shutdown() interface must only be called from a
+** single thread.  All open [database connections] must be closed and all
+** other SQLite resources must be deallocated prior to invoking
+** sqlite3_shutdown().
+**
+** Among other things, ^sqlite3_initialize() will invoke
+** sqlite3_os_init().  Similarly, ^sqlite3_shutdown()
+** will invoke sqlite3_os_end().
+**
+** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** ^If for some reason, sqlite3_initialize() is unable to initialize
+** the library (perhaps it is unable to allocate a needed resource such
+** as a mutex) it returns an [error code] other than [SQLITE_OK].
+**
+** ^The sqlite3_initialize() routine is called internally by many other
+** SQLite interfaces so that an application usually does not need to
+** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
+** calls sqlite3_initialize() so the SQLite library will be automatically
+** initialized when [sqlite3_open()] is called if it has not be initialized
+** already.  ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
+** compile-time option, then the automatic calls to sqlite3_initialize()
+** are omitted and the application must call sqlite3_initialize() directly
+** prior to using any other SQLite interface.  For maximum portability,
+** it is recommended that applications always invoke sqlite3_initialize()
+** directly prior to using any other SQLite interface.  Future releases
+** of SQLite may require this.  In other words, the behavior exhibited
+** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
+** default behavior in some future release of SQLite.
+**
+** The sqlite3_os_init() routine does operating-system specific
+** initialization of the SQLite library.  The sqlite3_os_end()
+** routine undoes the effect of sqlite3_os_init().  Typical tasks

+**
+** Note that SQLite comes with several [built-in memory allocators]
+** that are perfectly adequate for the overwhelming majority of applications
+** and that this object is only useful to a tiny minority of applications
+** with specialized memory allocation requirements.  This object is
+** also used during testing of SQLite in order to specify an alternative
+** memory allocator that simulates memory out-of-memory conditions in
+** order to verify that SQLite recovers gracefully from such
+** conditions.
+**
+** The xMalloc, xRealloc, and xFree methods must work like the
+** malloc(), realloc() and free() functions from the standard C library.
+** ^SQLite guarantees that the second argument to

+**
+** xSize should return the allocated size of a memory allocation
+** previously obtained from xMalloc or xRealloc.  The allocated size
+** is always at least as big as the requested size but may be larger.
+**
+** The xRoundup method returns what would be the allocated size of
+** a memory allocation given a particular requested size.  Most memory
+** allocators round up memory allocations at least to the next multiple
+** of 8.  Some allocators round up to a larger multiple or to a power of 2.
+** Every memory allocation request coming in through [sqlite3_malloc()]
+** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0, 
+** that causes the corresponding memory allocation to fail.
+**
+** The xInit method initializes the memory allocator.  For example,

+** CAPI3REF: Convenience Routines For Running Queries
+** METHOD: sqlite3
+**
+** This is a legacy interface that is preserved for backwards compatibility.
+** Use of this interface is not recommended.
+**
+** Definition: A <b>result table</b> is memory data structure created by the
+** [sqlite3_get_table()] interface.  A result table records the
+** complete query results from one or more queries.
+**
+** The table conceptually has a number of rows and columns.  But
+** these numbers are not part of the result table itself.  These
+** numbers are obtained separately.  Let N be the number of rows
+** and M be the number of columns.
+**
+** A result table is an array of pointers to zero-terminated UTF-8 strings.
+** There are (N+1)*M elements in the array.  The first M pointers point
+** to zero-terminated strings that  contain the names of the columns.
+** The remaining entries all point to query results.  NULL values result
+** in NULL pointers.  All other values are in their UTF-8 zero-terminated
+** string representation as returned by [sqlite3_column_text()].
+**
+** A result table might consist of one or more memory allocations.
+** It is not safe to pass a result table directly to [sqlite3_free()].
+** A result table should be deallocated using [sqlite3_free_table()].
+**
+** ^(As an example of the result table format, suppose a query result
+** is as follows:
+**
+** <blockquote><pre>
+**        Name        | Age
+**        -----------------------
+**        Alice       | 43
+**        Bob         | 28
+**        Cindy       | 21
+** </pre></blockquote>
+**
+** There are two columns (M==2) and three rows (N==3).  Thus the
+** result table has 8 entries.  Suppose the result table is stored
+** in an array named azResult.  Then azResult holds this content:
+**
+** <blockquote><pre>
+**        azResult&#91;0] = "Name";
+**        azResult&#91;1] = "Age";
+**        azResult&#91;2] = "Alice";
+**        azResult&#91;3] = "43";
+**        azResult&#91;4] = "Bob";
+**        azResult&#91;5] = "28";
+**        azResult&#91;6] = "Cindy";
+**        azResult&#91;7] = "21";
+** </pre></blockquote>)^
+**
+** ^The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter and returns a result table to the
+** pointer given in its 3rd parameter.
+**

+** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
+** function must not try to call [sqlite3_free()] directly.  Only
+** [sqlite3_free_table()] is able to release the memory properly and safely.
+**
+** The sqlite3_get_table() interface is implemented as a wrapper around
+** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite.  It uses only the public

+** CAPI3REF: Memory Allocation Subsystem
+**
+** The SQLite core uses these three routines for all of its own
+** internal memory allocation needs. "Core" in the previous sentence
+** does not include operating-system specific [VFS] implementation.  The
+** Windows VFS uses native malloc() and free() for some operations.
+**
+** ^The sqlite3_malloc() routine returns a pointer to a block
+** of memory at least N bytes in length, where N is the parameter.
+** ^If sqlite3_malloc() is unable to obtain sufficient free
+** memory, it returns a NULL pointer.  ^If the parameter N to
+** sqlite3_malloc() is zero or negative then sqlite3_malloc() returns
+** a NULL pointer.
+**
+** ^The sqlite3_malloc64(N) routine works just like
+** sqlite3_malloc(N) except that N is an unsigned 64-bit integer instead
+** of a signed 32-bit integer.
+**
+** ^Calling sqlite3_free() with a pointer previously returned
+** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
+** that it might be reused.  ^The sqlite3_free() routine is
+** a no-op if is called with a NULL pointer.  Passing a NULL pointer
+** to sqlite3_free() is harmless.  After being freed, memory
+** should neither be read nor written.  Even reading previously freed
+** memory might result in a segmentation fault or other severe error.
+** Memory corruption, a segmentation fault, or other severe error
+** might result if sqlite3_free() is called with a non-NULL pointer that
+** was not obtained from sqlite3_malloc() or sqlite3_realloc().
+**
+** ^The sqlite3_realloc(X,N) interface attempts to resize a
+** prior memory allocation X to be at least N bytes.
+** ^If the X parameter to sqlite3_realloc(X,N)
+** is a NULL pointer then its behavior is identical to calling
+** sqlite3_malloc(N).
+** ^If the N parameter to sqlite3_realloc(X,N) is zero or
+** negative then the behavior is exactly the same as calling
+** sqlite3_free(X).
+** ^sqlite3_realloc(X,N) returns a pointer to a memory allocation
+** of at least N bytes in size or NULL if insufficient memory is available.
+** ^If M is the size of the prior allocation, then min(N,M) bytes
+** of the prior allocation are copied into the beginning of buffer returned
+** by sqlite3_realloc(X,N) and the prior allocation is freed.
+** ^If sqlite3_realloc(X,N) returns NULL and N is positive, then the
+** prior allocation is not freed.
+**
+** ^The sqlite3_realloc64(X,N) interfaces works the same as
+** sqlite3_realloc(X,N) except that N is a 64-bit unsigned integer instead
+** of a 32-bit signed integer.
+**
+** ^If X is a memory allocation previously obtained from sqlite3_malloc(),
+** sqlite3_malloc64(), sqlite3_realloc(), or sqlite3_realloc64(), then
+** sqlite3_msize(X) returns the size of that memory allocation in bytes.
+** ^The value returned by sqlite3_msize(X) might be larger than the number
+** of bytes requested when X was allocated.  ^If X is a NULL pointer then
+** sqlite3_msize(X) returns zero.  If X points to something that is not
+** the beginning of memory allocation, or if it points to a formerly
+** valid memory allocation that has now been freed, then the behavior
+** of sqlite3_msize(X) is undefined and possibly harmful.
+**
+** ^The memory returned by sqlite3_malloc(), sqlite3_realloc(),

+** METHOD: sqlite3
+** KEYWORDS: {authorizer callback}
+**
+** ^This routine registers an authorizer callback with a particular
+** [database connection], supplied in the first argument.
+** ^The authorizer callback is invoked as SQL statements are being compiled
+** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
+** [sqlite3_prepare_v3()], [sqlite3_prepare16()], [sqlite3_prepare16_v2()],
+** and [sqlite3_prepare16_v3()].  ^At various
+** points during the compilation process, as logic is being created
+** to perform various actions, the authorizer callback is invoked to
+** see if those actions are allowed.  ^The authorizer callback should
+** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
+** specific action but allow the SQL statement to continue to be
+** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
+** rejected with an error.  ^If the authorizer callback returns
+** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
+** then the [sqlite3_prepare_v2()] or equivalent call that triggered
+** the authorizer will fail with an error message.
+**
+** When the callback returns [SQLITE_OK], that means the operation
+** requested is ok.  ^When the callback returns [SQLITE_DENY], the
+** [sqlite3_prepare_v2()] or equivalent call that triggered the
+** authorizer will fail with an error message explaining that
+** access is denied. 
+**
+** ^The first parameter to the authorizer callback is a copy of the third
+** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
+** to the callback is an integer [SQLITE_COPY | action code] that specifies
+** the particular action to be authorized. ^The third through sixth parameters
+** to the callback are either NULL pointers or zero-terminated strings
+** that contain additional details about the action to be authorized.
+** Applications must always be prepared to encounter a NULL pointer in any
+** of the third through the sixth parameters of the authorization callback.
+**
+** ^If the action code is [SQLITE_READ]
+** and the callback returns [SQLITE_IGNORE] then the
+** [prepared statement] statement is constructed to substitute
+** a NULL value in place of the table column that would have
+** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
+** return can be used to deny an untrusted user access to individual
+** columns of a table.
+** ^When a table is referenced by a [SELECT] but no column values are
+** extracted from that table (for example in a query like
+** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
+** is invoked once for that table with a column name that is an empty string.
+** ^If the action code is [SQLITE_DELETE] and the callback returns
+** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
+** [truncate optimization] is disabled and all rows are deleted individually.
+**
+** An authorizer is used when [sqlite3_prepare | preparing]
+** SQL statements from an untrusted source, to ensure that the SQL statements
+** do not try to access data they are not allowed to see, or that they do not
+** try to execute malicious statements that damage the database.  For
+** example, an application may allow a user to enter arbitrary
+** SQL queries for evaluation by a database.  But the application does
+** not want the user to be able to make arbitrary changes to the
+** database.  An authorizer could then be put in place while the
+** user-entered SQL is being [sqlite3_prepare | prepared] that
+** disallows everything except [SELECT] statements.
+**
+** Applications that need to process SQL from untrusted sources
+** might also consider lowering resource limits using [sqlite3_limit()]
+** and limiting database size using the [max_page_count] [PRAGMA]
+** in addition to using an authorizer.
+**
+** ^(Only a single authorizer can be in place on a database connection
+** at a time.  Each call to sqlite3_set_authorizer overrides the
+** previous call.)^  ^Disable the authorizer by installing a NULL callback.
+** The authorizer is disabled by default.
+**

+** ^When [sqlite3_prepare_v2()] is used to prepare a statement, the
+** statement might be re-prepared during [sqlite3_step()] due to a 
+** schema change.  Hence, the application should ensure that the
+** correct authorizer callback remains in place during the [sqlite3_step()].
+**
+** ^Note that the authorizer callback is invoked only during
+** [sqlite3_prepare()] or its variants.  Authorization is not

+** [[URI filenames in sqlite3_open()]] <h3>URI Filenames</h3>
+**
+** ^If [URI filename] interpretation is enabled, and the filename argument
+** begins with "file:", then the filename is interpreted as a URI. ^URI
+** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
+** set in the third argument to sqlite3_open_v2(), or if it has
+** been enabled globally using the [SQLITE_CONFIG_URI] option with the
+** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
+** URI filename interpretation is turned off
+** by default, but future releases of SQLite might enable URI filename
+** interpretation by default.  See "[URI filenames]" for additional
+** information.
+**
+** URI filenames are parsed according to RFC 3986. ^If the URI contains an
+** authority, then it must be either an empty string or the string 
+** "localhost". ^If the authority is not an empty string or "localhost", an 
+** error is returned to the caller. ^The fragment component of a URI, if 
+** present, is ignored.
+**
+** ^SQLite uses the path component of the URI as the name of the disk file
+** which contains the database. ^If the path begins with a '/' character, 
+** then it is interpreted as an absolute path. ^If the path does not begin 
+** with a '/' (meaning that the authority section is omitted from the URI)
+** then the path is interpreted as a relative path. 
+** ^(On windows, the first component of an absolute path 
+** is a drive specification (e.g. "C:").)^
+**
+** [[core URI query parameters]]
+** The query component of a URI may contain parameters that are interpreted
+** either by SQLite itself, or by a [VFS | custom VFS implementation].
+** SQLite and its built-in [VFSes] interpret the
+** following query parameters:
+**
+** <ul>
+**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
+**     a VFS object that provides the operating system interface that should
+**     be used to access the database file on disk. ^If this option is set to
+**     an empty string the default VFS object is used. ^Specifying an unknown
+**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
+**     present, then the VFS specified by the option takes precedence over
+**     the value passed as the fourth parameter to sqlite3_open_v2().
+**
+**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
+**     "rwc", or "memory". Attempting to set it to any other value is
+**     an error)^. 
+**     ^If "ro" is specified, then the database is opened for read-only 
+**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the 
+**     third argument to sqlite3_open_v2(). ^If the mode option is set to 
+**     "rw", then the database is opened for read-write (but not create) 
+**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had 
+**     been set. ^Value "rwc" is equivalent to setting both 
+**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
+**     set to "memory" then a pure [in-memory database] that never reads
+**     or writes from disk is used. ^It is an error to specify a value for
+**     the mode parameter that is less restrictive than that specified by
+**     the flags passed in the third parameter to sqlite3_open_v2().
+**
+**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
+**     "private". ^Setting it to "shared" is equivalent to setting the
+**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
+**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is 
+**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
+**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
+**     a URI filename, its value overrides any behavior requested by setting
+**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
+**
+**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
+**     [powersafe overwrite] property does or does not apply to the
+**     storage media on which the database file resides.
+**
+**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
+**     which if set disables file locking in rollback journal modes.  This
+**     is useful for accessing a database on a filesystem that does not
+**     support locking.  Caution:  Database corruption might result if two
+**     or more processes write to the same database and any one of those
+**     processes uses nolock=1.
+**
+**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
+**     parameter that indicates that the database file is stored on
+**     read-only media.  ^When immutable is set, SQLite assumes that the
+**     database file cannot be changed, even by a process with higher
+**     privilege, and so the database is opened read-only and all locking
+**     and change detection is disabled.  Caution: Setting the immutable
+**     property on a database file that does in fact change can result
+**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
+**     See also: [SQLITE_IOCAP_IMMUTABLE].
+**       
+** </ul>
+**
+** ^Specifying an unknown parameter in the query component of a URI is not an
+** error.  Future versions of SQLite might understand additional query
+** parameters.  See "[query parameters with special meaning to SQLite]" for
+** additional information.

+** CAPI3REF: Obtain Values For URI Parameters
+**
+** These are utility routines, useful to [VFS|custom VFS implementations],
+** that check if a database file was a URI that contained a specific query 
+** parameter, and if so obtains the value of that query parameter.
+**
+** The first parameter to these interfaces (hereafter referred to
+** as F) must be one of:
+** <ul>
+** <li> A database filename pointer created by the SQLite core and
+** passed into the xOpen() method of a VFS implemention, or
+** <li> A filename obtained from [sqlite3_db_filename()], or
+** <li> A new filename constructed using [sqlite3_create_filename()].
+** </ul>
+** If the F parameter is not one of the above, then the behavior is
+** undefined and probably undesirable.  Older versions of SQLite were
+** more tolerant of invalid F parameters than newer versions.
+**
+** If F is a suitable filename (as described in the previous paragraph)
+** and if P is the name of the query parameter, then
+** sqlite3_uri_parameter(F,P) returns the value of the P
+** parameter if it exists or a NULL pointer if P does not appear as a 
+** query parameter on F.  If P is a query parameter of F and it
+** has no explicit value, then sqlite3_uri_parameter(F,P) returns
+** a pointer to an empty string.
+**
+** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
+** parameter and returns true (1) or false (0) according to the value
+** of P.  The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
+** value of query parameter P is one of "yes", "true", or "on" in any
+** case or if the value begins with a non-zero number.  The 
+** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
+** query parameter P is one of "no", "false", or "off" in any case or
+** if the value begins with a numeric zero.  If P is not a query
+** parameter on F or if the value of P does not match any of the
+** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
+**
+** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
+** 64-bit signed integer and returns that integer, or D if P does not
+** exist.  If the value of P is something other than an integer, then
+** zero is returned.
+**
+** The sqlite3_uri_key(F,N) returns a pointer to the name (not
+** the value) of the N-th query parameter for filename F, or a NULL
+** pointer if N is less than zero or greater than the number of query
+** parameters minus 1.  The N value is zero-based so N should be 0 to obtain
+** the name of the first query parameter, 1 for the second parameter, and
+** so forth.
+** 
+** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
+** sqlite3_uri_boolean(F,P,B) returns B.  If F is not a NULL pointer and
+** is not a database file pathname pointer that the SQLite core passed
+** into the xOpen VFS method, then the behavior of this routine is undefined
+** and probably undesirable.
+**
+** Beginning with SQLite [version 3.31.0] ([dateof:3.31.0]) the input F
+** parameter can also be the name of a rollback journal file or WAL file
+** in addition to the main database file.  Prior to version 3.31.0, these
+** routines would only work if F was the name of the main database file.
+** When the F parameter is the name of the rollback journal or WAL file,

+** CAPI3REF: Compiling An SQL Statement
+** KEYWORDS: {SQL statement compiler}
+** METHOD: sqlite3
+** CONSTRUCTOR: sqlite3_stmt
+**
+** To execute an SQL statement, it must first be compiled into a byte-code
+** program using one of these routines.  Or, in other words, these routines
+** are constructors for the [prepared statement] object.
+**
+** The preferred routine to use is [sqlite3_prepare_v2()].  The
+** [sqlite3_prepare()] interface is legacy and should be avoided.
+** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
+** for special purposes.
+**
+** The use of the UTF-8 interfaces is preferred, as SQLite currently
+** does all parsing using UTF-8.  The UTF-16 interfaces are provided
+** as a convenience.  The UTF-16 interfaces work by converting the
+** input text into UTF-8, then invoking the corresponding UTF-8 interface.
+**
+** The first argument, "db", is a [database connection] obtained from a
+** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
+** [sqlite3_open16()].  The database connection must not have been closed.
+**
+** The second argument, "zSql", is the statement to be compiled, encoded
+** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
+** and sqlite3_prepare_v3()
+** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() use UTF-16.
+**
+** ^If the nByte argument is negative, then zSql is read up to the
+** first zero terminator. ^If nByte is positive, then it is the
+** number of bytes read from zSql.  ^If nByte is zero, then no prepared
+** statement is generated.
+** If the caller knows that the supplied string is nul-terminated, then
+** there is a small performance advantage to passing an nByte parameter that
+** is the number of bytes in the input string <i>including</i>
+** the nul-terminator.
+**
+** ^If pzTail is not NULL then *pzTail is made to point to the first byte
+** past the end of the first SQL statement in zSql.  These routines only
+** compile the first statement in zSql, so *pzTail is left pointing to
+** what remains uncompiled.
+**
+** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
+** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
+** to NULL.  ^If the input text contains no SQL (if the input is an empty
+** string or a comment) then *ppStmt is set to NULL.
+** The calling procedure is responsible for deleting the compiled
+** SQL statement using [sqlite3_finalize()] after it has finished with it.
+** ppStmt may not be NULL.
+**
+** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
+** otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
+** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
+** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
+** are retained for backwards compatibility, but their use is discouraged.
+** ^In the "vX" interfaces, the prepared statement
+** that is returned (the [sqlite3_stmt] object) contains a copy of the
+** original SQL text. This causes the [sqlite3_step()] interface to
+** behave differently in three ways:
+**
+** <ol>
+** <li>
+** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
+** always used to do, [sqlite3_step()] will automatically recompile the SQL
+** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
+** retries will occur before sqlite3_step() gives up and returns an error.
+** </li>
+**
+** <li>
+** ^When an error occurs, [sqlite3_step()] will return one of the detailed
+** [error codes] or [extended error codes].  ^The legacy behavior was that
+** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
+** and the application would have to make a second call to [sqlite3_reset()]
+** in order to find the underlying cause of the problem. With the "v2" prepare
+** interfaces, the underlying reason for the error is returned immediately.
+** </li>
+**
+** <li>
+** ^If the specific value bound to a [parameter | host parameter] in the 
+** WHERE clause might influence the choice of query plan for a statement,
+** then the statement will be automatically recompiled, as if there had been 
+** a schema change, on the first [sqlite3_step()] call following any change
+** to the [sqlite3_bind_text | bindings] of that [parameter]. 
+** ^The specific value of a WHERE-clause [parameter] might influence the 
+** choice of query plan if the parameter is the left-hand side of a [LIKE]
+** or [GLOB] operator or if the parameter is compared to an indexed column
+** and the [SQLITE_ENABLE_STAT4] compile-time option is enabled.
+** </li>
+** </ol>
+**
+** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
+** the extra prepFlags parameter, which is a bit array consisting of zero or
+** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags.  ^The
+** sqlite3_prepare_v2() interface works exactly the same as
+** sqlite3_prepare_v3() with a zero prepFlags parameter.

+** UTF16 input text is determined by the byte-order mark (BOM, U+FEFF)
+** found in first character, which is removed, or in the absence of a BOM
+** the byte order is the native byte order of the host
+** machine for sqlite3_bind_text16() or the byte order specified in
+** the 6th parameter for sqlite3_bind_text64().)^ 
+** ^If UTF16 input text contains invalid unicode
+** characters, then SQLite might change those invalid characters
+** into the unicode replacement character: U+FFFD.
+**
+** ^(In those routines that have a fourth argument, its value is the
+** number of bytes in the parameter.  To be clear: the value is the
+** number of <u>bytes</u> in the value, not the number of characters.)^
+** ^If the fourth parameter to sqlite3_bind_text() or sqlite3_bind_text16()
+** is negative, then the length of the string is
+** the number of bytes up to the first zero terminator.
+** If the fourth parameter to sqlite3_bind_blob() is negative, then
+** the behavior is undefined.
+** If a non-negative fourth parameter is provided to sqlite3_bind_text()
+** or sqlite3_bind_text16() or sqlite3_bind_text64() then
+** that parameter must be the byte offset
+** where the NUL terminator would occur assuming the string were NUL
+** terminated.  If any NUL characters occurs at byte offsets less than 
+** the value of the fourth parameter then the resulting string value will
+** contain embedded NULs.  The result of expressions involving strings
+** with embedded NULs is undefined.
+**
+** ^The fifth argument to the BLOB and string binding interfaces
+** is a destructor used to dispose of the BLOB or
+** string after SQLite has finished with it.  ^The destructor is called
+** to dispose of the BLOB or string even if the call to the bind API fails,
+** except the destructor is not called if the third parameter is a NULL
+** pointer or the fourth parameter is negative.
+** ^If the fifth argument is
+** the special value [SQLITE_STATIC], then SQLite assumes that the
+** information is in static, unmanaged space and does not need to be freed.
+** ^If the fifth argument has the value [SQLITE_TRANSIENT], then
+** SQLite makes its own private copy of the data immediately, before
+** the sqlite3_bind_*() routine returns.
+**
+** ^The sixth argument to sqlite3_bind_text64() must be one of
+** [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE]
+** to specify the encoding of the text in the third parameter.  If
+** the sixth argument to sqlite3_bind_text64() is not one of the
+** allowed values shown above, or if the text encoding is different
+** from the encoding specified by the sixth parameter, then the behavior
+** is undefined.
+**
+** ^The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
+** is filled with zeroes.  ^A zeroblob uses a fixed amount of memory
+** (just an integer to hold its size) while it is being processed.
+** Zeroblobs are intended to serve as placeholders for BLOBs whose
+** content is later written using
+** [sqlite3_blob_open | incremental BLOB I/O] routines.
+** ^A negative value for the zeroblob results in a zero-length BLOB.
+**
+** ^The sqlite3_bind_pointer(S,I,P,T,D) routine causes the I-th parameter in
+** [prepared statement] S to have an SQL value of NULL, but to also be
+** associated with the pointer P of type T.  ^D is either a NULL pointer or
+** a pointer to a destructor function for P. ^SQLite will invoke the
+** destructor D with a single argument of P when it is finished using
+** P.  The T parameter should be a static string, preferably a string
+** literal. The sqlite3_bind_pointer() routine is part of the
+** [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^If any of the sqlite3_bind_*() routines are called with a NULL pointer
+** for the [prepared statement] or with a prepared statement for which
+** [sqlite3_step()] has been called more recently than [sqlite3_reset()],
+** then the call will return [SQLITE_MISUSE].  If any sqlite3_bind_()
+** routine is passed a [prepared statement] that has been finalized, the
+** result is undefined and probably harmful.
+**
+** ^Bindings are not cleared by the [sqlite3_reset()] routine.
+** ^Unbound parameters are interpreted as NULL.
+**
+** ^The sqlite3_bind_* routines return [SQLITE_OK] on success or an
+** [error code] if anything goes wrong.
+** ^[SQLITE_TOOBIG] might be returned if the size of a string or BLOB
+** exceeds limits imposed by [sqlite3_limit]([SQLITE_LIMIT_LENGTH]) or
+** [SQLITE_MAX_LENGTH].
+** ^[SQLITE_RANGE] is returned if the parameter
+** index is out of range.  ^[SQLITE_NOMEM] is returned if malloc() fails.

+** or occurs outside of an explicit transaction, then you can retry the
+** statement.  If the statement is not a [COMMIT] and occurs within an
+** explicit transaction then you should rollback the transaction before
+** continuing.
+**
+** ^[SQLITE_DONE] means that the statement has finished executing
+** successfully.  sqlite3_step() should not be called again on this virtual
+** machine without first calling [sqlite3_reset()] to reset the virtual
+** machine back to its initial state.
+**
+** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
+** is returned each time a new row of data is ready for processing by the
+** caller. The values may be accessed using the [column access functions].
+** sqlite3_step() is called again to retrieve the next row of data.

+** ^[SQLITE_ERROR] means that a run-time error (such as a constraint

+** can be obtained by calling [sqlite3_reset()] on the
+** [prepared statement].  ^In the "v2" interface,
+** the more specific error code is returned directly by sqlite3_step().
+**
+** [SQLITE_MISUSE] means that the this routine was called inappropriately.
+** Perhaps it was called on a [prepared statement] that has
+** already been [sqlite3_finalize | finalized] or on one that had
+** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
+** be the case that the same database connection is being used by two or

+** sqlite3_step().  Failure to reset the prepared statement using 
+** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from

+** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
+** that was returned from [sqlite3_prepare_v2()] or one of its variants)
+** and the second argument is the index of the column for which information
+** should be returned. ^The leftmost column of the result set has the index 0.
+** ^The number of columns in the result can be determined using
+** [sqlite3_column_count()].
+**
+** If the SQL statement does not currently point to a valid row, or if the
+** column index is out of range, the result is undefined.
+** These routines may only be called when the most recent call to
+** [sqlite3_step()] has returned [SQLITE_ROW] and neither
+** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
+** If any of these routines are called after [sqlite3_reset()] or
+** [sqlite3_finalize()] or after [sqlite3_step()] has returned
+** something other than [SQLITE_ROW], the results are undefined.
+** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
+** are called from a different thread while any of these routines
+** are pending, then the results are undefined.
+**
+** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
+** each return the value of a result column in a specific data format.  If
+** the result column is not initially in the requested format (for example,
+** if the query returns an integer but the sqlite3_column_text() interface
+** is used to extract the value) then an automatic type conversion is performed.
+**
+** ^The sqlite3_column_type() routine returns the
+** [SQLITE_INTEGER | datatype code] for the initial data type
+** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
+** The return value of sqlite3_column_type() can be used to decide which
+** of the first six interface should be used to extract the column value.
+** The value returned by sqlite3_column_type() is only meaningful if no
+** automatic type conversions have occurred for the value in question.  
+** After a type conversion, the result of calling sqlite3_column_type()
+** is undefined, though harmless.  Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
+** or sqlite3_column_bytes16() interfaces can be used to determine the size
+** of that BLOB or string.
+**
+** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
+** the string to UTF-8 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
+**
+** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
+** routine returns the number of bytes in that BLOB or string.
+** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
+** the string to UTF-16 and then returns the number of bytes.
+** ^If the result is a numeric value then sqlite3_column_bytes16() uses
+** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
+** the number of bytes in that string.
+** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
+**
+** ^The values returned by [sqlite3_column_bytes()] and 
+** [sqlite3_column_bytes16()] do not include the zero terminators at the end
+** of the string.  ^For clarity: the values returned by
+** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
+** bytes in the string, not the number of characters.
+**
+** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even empty strings, are always zero-terminated.  ^The return
+** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
+**
+** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object.  In a multithreaded environment,
+** an unprotected sqlite3_value object may only be used safely with
+** [sqlite3_bind_value()] and [sqlite3_result_value()].
+** If the [unprotected sqlite3_value] object returned by
+** [sqlite3_column_value()] is used in any other way, including calls
+** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
+** or [sqlite3_value_bytes()], the behavior is not threadsafe.
+** Hence, the sqlite3_column_value() interface
+** is normally only useful within the implementation of 
+** [application-defined SQL functions] or [virtual tables], not within
+** top-level application code.
+**
+** The these routines may attempt to convert the datatype of the result.
+** ^For example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to perform the
+** conversion automatically.  ^(The following table details the conversions
+** that are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
+**

+**
+** Note that when type conversions occur, pointers returned by prior
+** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
+** sqlite3_column_text16() may be invalidated.
+** Type conversions and pointer invalidations might occur
+** in the following cases:
+**
+** <ul>
+** <li> The initial content is a BLOB and sqlite3_column_text() or
+**      sqlite3_column_text16() is called.  A zero-terminator might
+**      need to be added to the string.</li>
+** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
+**      sqlite3_column_text16() is called.  The content must be converted
+**      to UTF-16.</li>
+** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
+**      sqlite3_column_text() is called.  The content must be converted
+**      to UTF-8.</li>
+** </ul>
+**
+** ^Conversions between UTF-16be and UTF-16le are always done in place and do
+** not invalidate a prior pointer, though of course the content of the buffer
+** that the prior pointer references will have been modified.  Other kinds
+** of conversion are done in place when it is possible, but sometimes they
+** are not possible and in those cases prior pointers are invalidated.
+**
+** The safest policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** In other words, you should call sqlite3_column_text(),
+** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
+** into the desired format, then invoke sqlite3_column_bytes() or
+** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
+** to sqlite3_column_text() or sqlite3_column_blob() with calls to
+** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
+** with calls to sqlite3_column_bytes().
+**
+** ^The pointers returned are valid until a type conversion occurs as
+** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
+** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
+** and BLOBs is freed automatically.  Do not pass the pointers returned
+** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** As long as the input parameters are correct, these routines will only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_column_blob()
+** <li> sqlite3_column_text()
+** <li> sqlite3_column_text16()
+** <li> sqlite3_column_bytes()
+** <li> sqlite3_column_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** KEYWORDS: {function creation routines}
+** METHOD: sqlite3
+**
+** ^These functions (collectively known as "function creation routines")
+** are used to add SQL functions or aggregates or to redefine the behavior
+** of existing SQL functions or aggregates. The only differences between
+** the three "sqlite3_create_function*" routines are the text encoding 
+** expected for the second parameter (the name of the function being 
+** created) and the presence or absence of a destructor callback for
+** the application data pointer. Function sqlite3_create_window_function()
+** is similar, but allows the user to supply the extra callback functions
+** needed by [aggregate window functions].
+**
+** ^The first parameter is the [database connection] to which the SQL
+** function is to be added.  ^If an application uses more than one database
+** connection then application-defined SQL functions must be added
+** to each database connection separately.
+**
+** ^The second parameter is the name of the SQL function to be created or
+** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
+** representation, exclusive of the zero-terminator.  ^Note that the name
+** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.  
+** ^Any attempt to create a function with a longer name
+** will result in [SQLITE_MISUSE] being returned.
+**
+** ^The third parameter (nArg)
+** is the number of arguments that the SQL function or
+** aggregate takes. ^If this parameter is -1, then the SQL function or
+** aggregate may take any number of arguments between 0 and the limit
+** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
+** parameter is less than -1 or greater than 127 then the behavior is
+** undefined.
+**
+** ^The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters.  The application should set this parameter to
+** [SQLITE_UTF16LE] if the function implementation invokes 
+** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
+** implementation invokes [sqlite3_value_text16be()] on an input, or
+** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
+** otherwise.  ^The same SQL function may be registered multiple times using
+** different preferred text encodings, with different implementations for
+** each encoding.
+** ^When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+**
+** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
+** to signal that the function will always return the same result given
+** the same inputs within a single SQL statement.  Most SQL functions are
+** deterministic.  The built-in [random()] SQL function is an example of a
+** function that is not deterministic.  The SQLite query planner is able to
+** perform additional optimizations on deterministic functions, so use
+** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
+**
+** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
+** flag, which if present prevents the function from being invoked from
+** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
+** index expressions, or the WHERE clause of partial indexes.
+**
+** <span style="background-color:#ffff90;">
+** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
+** all application-defined SQL functions that do not need to be
+** used inside of triggers, view, CHECK constraints, or other elements of
+** the database schema.  This flags is especially recommended for SQL 
+** functions that have side effects or reveal internal application state.
+** Without this flag, an attacker might be able to modify the schema of
+** a database file to include invocations of the function with parameters
+** chosen by the attacker, which the application will then execute when
+** the database file is opened and read.
+** </span>
+**
+** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
+** function can gain access to this pointer using [sqlite3_user_data()].)^
+**
+** ^The sixth, seventh and eighth parameters passed to the three
+** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
+** pointers to C-language functions that implement the SQL function or
+** aggregate. ^A scalar SQL function requires an implementation of the xFunc
+** callback only; NULL pointers must be passed as the xStep and xFinal
+** parameters. ^An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
+** SQL function or aggregate, pass NULL pointers for all three function
+** callbacks.
+**
+** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue 
+** and xInverse) passed to sqlite3_create_window_function are pointers to
+** C-language callbacks that implement the new function. xStep and xFinal
+** must both be non-NULL. xValue and xInverse may either both be NULL, in
+** which case a regular aggregate function is created, or must both be 
+** non-NULL, in which case the new function may be used as either an aggregate
+** or aggregate window function. More details regarding the implementation
+** of aggregate window functions are 
+** [user-defined window functions|available here].
+**
+** ^(If the final parameter to sqlite3_create_function_v2() or
+** sqlite3_create_window_function() is not NULL, then it is destructor for
+** the application data pointer. The destructor is invoked when the function 
+** is deleted, either by being overloaded or when the database connection 
+** closes.)^ ^The destructor is also invoked if the call to 
+** sqlite3_create_function_v2() fails.  ^When the destructor callback is
+** invoked, it is passed a single argument which is a copy of the application
+** data pointer which was the fifth parameter to sqlite3_create_function_v2().
+**
+** ^It is permitted to register multiple implementations of the same
+** functions with the same name but with either differing numbers of
+** arguments or differing preferred text encodings.  ^SQLite will use
+** the implementation that most closely matches the way in which the
+** SQL function is used.  ^A function implementation with a non-negative
+** nArg parameter is a better match than a function implementation with
+** a negative nArg.  ^A function where the preferred text encoding
+** matches the database encoding is a better
+** match than a function where the encoding is different.  
+** ^A function where the encoding difference is between UTF16le and UTF16be
+** is a closer match than a function where the encoding difference is
+** between UTF8 and UTF16.
+**
+** ^Built-in functions may be overloaded by new application-defined functions.

+**
+** <b>Details:</b>
+**
+** These routines extract type, size, and content information from
+** [protected sqlite3_value] objects.  Protected sqlite3_value objects
+** are used to pass parameter information into the functions that
+** implement [application-defined SQL functions] and [virtual tables].
+**
+** These routines work only with [protected sqlite3_value] objects.
+** Any attempt to use these routines on an [unprotected sqlite3_value]
+** is not threadsafe.
+**
+** ^These routines work just like the corresponding [column access functions]
+** except that these routines take a single [protected sqlite3_value] object
+** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
+**
+** ^The sqlite3_value_text16() interface extracts a UTF-16 string
+** in the native byte-order of the host machine.  ^The
+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+** extract UTF-16 strings as big-endian and little-endian respectively.
+**
+** ^If [sqlite3_value] object V was initialized 
+** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
+** and if X and Y are strings that compare equal according to strcmp(X,Y),
+** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
+** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer() 
+** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
+**
+** ^(The sqlite3_value_type(V) interface returns the
+** [SQLITE_INTEGER | datatype code] for the initial datatype of the
+** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
+** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
+** Other interfaces might change the datatype for an sqlite3_value object.
+** For example, if the datatype is initially SQLITE_INTEGER and
+** sqlite3_value_text(V) is called to extract a text value for that
+** integer, then subsequent calls to sqlite3_value_type(V) might return
+** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
+** occurs is undefined and may change from one release of SQLite to the next.
+**
+** ^(The sqlite3_value_numeric_type() interface attempts to apply
+** numeric affinity to the value.  This means that an attempt is
+** made to convert the value to an integer or floating point.  If
+** such a conversion is possible without loss of information (in other
+** words, if the value is a string that looks like a number)
+** then the conversion is performed.  Otherwise no conversion occurs.
+** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
+**
+** ^Within the [xUpdate] method of a [virtual table], the
+** sqlite3_value_nochange(X) interface returns true if and only if
+** the column corresponding to X is unchanged by the UPDATE operation
+** that the xUpdate method call was invoked to implement and if
+** and the prior [xColumn] method call that was invoked to extracted
+** the value for that column returned without setting a result (probably
+** because it queried [sqlite3_vtab_nochange()] and found that the column
+** was unchanging).  ^Within an [xUpdate] method, any value for which
+** sqlite3_value_nochange(X) is true will in all other respects appear
+** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
+** than within an [xUpdate] method call for an UPDATE statement, then
+** the return value is arbitrary and meaningless.
+**
+** ^The sqlite3_value_frombind(X) interface returns non-zero if the
+** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
+** interfaces.  ^If X comes from an SQL literal value, or a table column,
+** or an expression, then sqlite3_value_frombind(X) returns zero.
+**
+** Please pay particular attention to the fact that the pointer returned
+** from [sqlite3_value_blob()], [sqlite3_value_text()], or
+** [sqlite3_value_text16()] can be invalidated by a subsequent call to
+** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
+** or [sqlite3_value_text16()].
+**
+** These routines must be called from the same thread as
+** the SQL function that supplied the [sqlite3_value*] parameters.
+**
+** As long as the input parameter is correct, these routines can only
+** fail if an out-of-memory error occurs during a format conversion.
+** Only the following subset of interfaces are subject to out-of-memory
+** errors:
+**
+** <ul>
+** <li> sqlite3_value_blob()
+** <li> sqlite3_value_text()
+** <li> sqlite3_value_text16()
+** <li> sqlite3_value_text16le()
+** <li> sqlite3_value_text16be()
+** <li> sqlite3_value_bytes()
+** <li> sqlite3_value_bytes16()
+** </ul>
+**
+** If an out-of-memory error occurs, then the return value from these
+** routines is the same as if the column had contained an SQL NULL value.
+** Valid SQL NULL returns can be distinguished from out-of-memory errors
+** by invoking the [sqlite3_errcode()] immediately after the suspect
+** return value is obtained and before any
+** other SQLite interface is called on the same [database connection].

+** Refer to the [SQL parameter] documentation for additional information.
+**
+** ^The sqlite3_result_blob() interface sets the result from

+** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
+** interfaces set the result of the application-defined function to be

+**
+** ^The sqlite3_result_double() interface sets the result from
+** an application-defined function to be a floating point value specified
+** by its 2nd argument.
+**
+** ^The sqlite3_result_error() and sqlite3_result_error16() functions
+** cause the implemented SQL function to throw an exception.
+** ^SQLite uses the string pointed to by the
+** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
+** as the text of an error message.  ^SQLite interprets the error
+** message string from sqlite3_result_error() as UTF-8. ^SQLite
+** interprets the string from sqlite3_result_error16() as UTF-16 using
+** the same [byte-order determination rules] as [sqlite3_bind_text16()].
+** ^If the third parameter to sqlite3_result_error()
+** or sqlite3_result_error16() is negative then SQLite takes as the error
+** message all text up through the first zero character.
+** ^If the third parameter to sqlite3_result_error() or
+** sqlite3_result_error16() is non-negative then SQLite takes that many
+** bytes (not characters) from the 2nd parameter as the error message.
+** ^The sqlite3_result_error() and sqlite3_result_error16()
+** routines make a private copy of the error message text before
+** they return.  Hence, the calling function can deallocate or
+** modify the text after they return without harm.
+** ^The sqlite3_result_error_code() function changes the error code
+** returned by SQLite as a result of an error in a function.  ^By default,
+** the error code is SQLITE_ERROR.  ^A subsequent call to sqlite3_result_error()
+** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
+**
+** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
+** error indicating that a string or BLOB is too long to represent.
+**
+** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
+** error indicating that a memory allocation failed.
+**
+** ^The sqlite3_result_int() interface sets the return value
+** of the application-defined function to be the 32-bit signed integer
+** value given in the 2nd argument.
+** ^The sqlite3_result_int64() interface sets the return value
+** of the application-defined function to be the 64-bit signed integer
+** value given in the 2nd argument.
+**
+** ^The sqlite3_result_null() interface sets the return value
+** of the application-defined function to be NULL.
+**
+** ^The sqlite3_result_text(), sqlite3_result_text16(),
+** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
+** set the return value of the application-defined function to be
+** a text string which is represented as UTF-8, UTF-16 native byte order,
+** UTF-16 little endian, or UTF-16 big endian, respectively.
+** ^The sqlite3_result_text64() interface sets the return value of an
+** application-defined function to be a text string in an encoding
+** specified by the fifth (and last) parameter, which must be one
+** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
+** ^SQLite takes the text result from the application from
+** the 2nd parameter of the sqlite3_result_text* interfaces.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is negative, then SQLite takes result text from the 2nd parameter
+** through the first zero character.
+** ^If the 3rd parameter to the sqlite3_result_text* interfaces
+** is non-negative, then as many bytes (not characters) of the text
+** pointed to by the 2nd parameter are taken as the application-defined
+** function result.  If the 3rd parameter is non-negative, then it
+** must be the byte offset into the string where the NUL terminator would
+** appear if the string where NUL terminated.  If any NUL characters occur
+** in the string at a byte offset that is less than the value of the 3rd
+** parameter, then the resulting string will contain embedded NULs and the
+** result of expressions operating on strings with embedded NULs is undefined.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
+** function as the destructor on the text or BLOB result when it has
+** finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
+** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
+** assumes that the text or BLOB result is in constant space and does not
+** copy the content of the parameter nor call a destructor on the content
+** when it has finished using that result.
+** ^If the 4th parameter to the sqlite3_result_text* interfaces
+** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
+** then SQLite makes a copy of the result into space obtained
+** from [sqlite3_malloc()] before it returns.
+**
+** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
+** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
+** when the encoding is not UTF8, if the input UTF16 begins with a
+** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
+** string and the rest of the string is interpreted according to the
+** byte-order specified by the BOM.  ^The byte-order specified by
+** the BOM at the beginning of the text overrides the byte-order
+** specified by the interface procedure.  ^So, for example, if
+** sqlite3_result_text16le() is invoked with text that begins
+** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
+** first two bytes of input are skipped and the remaining input
+** is interpreted as UTF16BE text.
+**
+** ^For UTF16 input text to the sqlite3_result_text16(),
+** sqlite3_result_text16be(), sqlite3_result_text16le(), and
+** sqlite3_result_text64() routines, if the text contains invalid
+** UTF16 characters, the invalid characters might be converted
+** into the unicode replacement character, U+FFFD.
+**
+** ^The sqlite3_result_value() interface sets the result of
+** the application-defined function to be a copy of the
+** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
+** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
+** so that the [sqlite3_value] specified in the parameter may change or
+** be deallocated after sqlite3_result_value() returns without harm.
+** ^A [protected sqlite3_value] object may always be used where an

+** kind of [sqlite3_value] object can be used with this interface.
+**
+** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
+** SQL NULL value, just like [sqlite3_result_null(C)], except that it

+** method of a [virtual table module].  The fields under **Inputs** are the
+** inputs to xBestIndex and are read-only.  xBestIndex inserts its
+** results into the **Outputs** fields.
+**
+** ^(The aConstraint[] array records WHERE clause constraints of the form:
+**
+** <blockquote>column OP expr</blockquote>
+**
+** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
+** stored in aConstraint[].op using one of the
+** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
+** ^(The index of the column is stored in
+** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
+** expr on the right-hand side can be evaluated (and thus the constraint
+** is usable) and false if it cannot.)^
+**
+** ^The optimizer automatically inverts terms of the form "expr OP column"
+** and makes other simplifications to the WHERE clause in an attempt to
+** get as many WHERE clause terms into the form shown above as possible.
+** ^The aConstraint[] array only reports WHERE clause terms that are
+** relevant to the particular virtual table being queried.
+**
+** ^Information about the ORDER BY clause is stored in aOrderBy[].
+** ^Each term of aOrderBy records a column of the ORDER BY clause.
+**
+** The colUsed field indicates which columns of the virtual table may be
+** required by the current scan. Virtual table columns are numbered from
+** zero in the order in which they appear within the CREATE TABLE statement
+** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
+** the corresponding bit is set within the colUsed mask if the column may be
+** required by SQLite. If the table has at least 64 columns and any column
+** to the right of the first 63 is required, then bit 63 of colUsed is also
+** set. In other words, column iCol may be required if the expression
+** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to 
+** non-zero.
+**
+** The [xBestIndex] method must fill aConstraintUsage[] with information
+** about what parameters to pass to xFilter.  ^If argvIndex>0 then
+** the right-hand side of the corresponding aConstraint[] is evaluated
+** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
+** is true, then the constraint is assumed to be fully handled by the
+** virtual table and might not be checked again by the byte code.)^ ^(The
+** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
+** is left in its default setting of false, the constraint will always be
+** checked separately in byte code.  If the omit flag is change to true, then
+** the constraint may or may not be checked in byte code.  In other words,
+** when the omit flag is true there is no guarantee that the constraint will
+** not be checked again using byte code.)^
+**
+** ^The idxNum and idxPtr values are recorded and passed into the
+** [xFilter] method.
+** ^[sqlite3_free()] is used to free idxPtr if and only if
+** needToFreeIdxPtr is true.
+**
+** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
+** the correct order to satisfy the ORDER BY clause so that no separate
+** sorting step is required.
+**
+** ^The estimatedCost value is an estimate of the cost of a particular
+** strategy. A cost of N indicates that the cost of the strategy is similar
+** to a linear scan of an SQLite table with N rows. A cost of log(N) 
+** indicates that the expense of the operation is similar to that of a
+** binary search on a unique indexed field of an SQLite table with N rows.
+**
+** ^The estimatedRows value is an estimate of the number of rows that
+** will be returned by the strategy.
+**
+** The xBestIndex method may optionally populate the idxFlags field with a 
+** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
+** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
+** assumes that the strategy may visit at most one row. 
+**
+** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
+** SQLite also assumes that if a call to the xUpdate() method is made as
+** part of the same statement to delete or update a virtual table row and the
+** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
+** any database changes. In other words, if the xUpdate() returns
+** SQLITE_CONSTRAINT, the database contents must be exactly as they were
+** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
+** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
+** the xUpdate method are automatically rolled back by SQLite.
+**
+** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
+** structure for SQLite [version 3.8.2] ([dateof:3.8.2]). 
+** If a virtual table extension is
+** used with an SQLite version earlier than 3.8.2, the results of attempting

+** to include crashing the application). The estimatedRows field should
+** therefore only be used if [sqlite3_libversion_number()] returns a
+** value greater than or equal to 3008002. Similarly, the idxFlags field
+** was added for [version 3.9.0] ([dateof:3.9.0]).

+** CAPI3REF: SQL Keyword Checking

+** whether or not a specific identifier needs to be escaped (for example,
+** by enclosing in double-quotes) so as not to confuse the parser.
+**
+** The sqlite3_keyword_count() interface returns the number of distinct
+** keywords understood by SQLite.
+**
+** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
+** makes *Z point to that keyword expressed as UTF8 and writes the number
+** of bytes in the keyword into *L.  The string that *Z points to is not
+** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
+** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
+** or L are NULL or invalid pointers then calls to
+** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
+**
+** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
+** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
+** if it is and zero if not.
+**
+** The parser used by SQLite is forgiving.  It is often possible to use
+** a keyword as an identifier as long as such use does not result in a
+** parsing ambiguity.  For example, the statement
+** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
+** creates a new table named "BEGIN" with three columns named
+** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
+** using keywords as identifiers.  Common techniques used to avoid keyword
+** name collisions include:
+** <ul>
+** <li> Put all identifier names inside double-quotes.  This is the official
+**      SQL way to escape identifier names.
+** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
+**      but it is what SQL Server does and so lots of programmers use this
+**      technique.
+** <li> Begin every identifier with the letter "Z" as no SQL keywords start
+**      with "Z".
+** <li> Include a digit somewhere in every identifier name.
+** </ul>
+**
+** Note that the number of keywords understood by SQLite can depend on
+** compile-time options.  For example, "VACUUM" is not a keyword if
+** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option.  Also,
+** new keywords may be added to future releases of SQLite.

+**
+** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
+** register an alternative page cache implementation by passing in an 
+** instance of the sqlite3_pcache_methods2 structure.)^
+** In many applications, most of the heap memory allocated by 
+** SQLite is used for the page cache.
+** By implementing a 
+** custom page cache using this API, an application can better control
+** the amount of memory consumed by SQLite, the way in which 
+** that memory is allocated and released, and the policies used to 
+** determine exactly which parts of a database file are cached and for 
+** how long.
+**
+** The alternative page cache mechanism is an
+** extreme measure that is only needed by the most demanding applications.
+** The built-in page cache is recommended for most uses.
+**
+** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config].  Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.)^
+**
+** [[the xInit() page cache method]]
+** ^(The xInit() method is called once for each effective 
+** call to [sqlite3_initialize()])^
+** (usually only once during the lifetime of the process). ^(The xInit()
+** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
+** The intent of the xInit() method is to set up global data structures 
+** required by the custom page cache implementation. 
+** ^(If the xInit() method is NULL, then the 
+** built-in default page cache is used instead of the application defined
+** page cache.)^
+**
+** [[the xShutdown() page cache method]]
+** ^The xShutdown() method is called by [sqlite3_shutdown()].
+** It can be used to clean up 
+** any outstanding resources before process shutdown, if required.
+** ^The xShutdown() method may be NULL.
+**
+** ^SQLite automatically serializes calls to the xInit method,
+** so the xInit method need not be threadsafe.  ^The
+** xShutdown method is only called from [sqlite3_shutdown()] so it does
+** not need to be threadsafe either.  All other methods must be threadsafe
+** in multithreaded applications.
+**
+** ^SQLite will never invoke xInit() more than once without an intervening
+** call to xShutdown().
+**
+** [[the xCreate() page cache methods]]
+** ^SQLite invokes the xCreate() method to construct a new cache instance.
+** SQLite will typically create one cache instance for each open database file,
+** though this is not guaranteed. ^The
+** first parameter, szPage, is the size in bytes of the pages that must
+** be allocated by the cache.  ^szPage will always a power of two.  ^The
+** second parameter szExtra is a number of bytes of extra storage 
+** associated with each page cache entry.  ^The szExtra parameter will
+** a number less than 250.  SQLite will use the
+** extra szExtra bytes on each page to store metadata about the underlying
+** database page on disk.  The value passed into szExtra depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** ^The third argument to xCreate(), bPurgeable, is true if the cache being
+** created will be used to cache database pages of a file stored on disk, or
+** false if it is used for an in-memory database. The cache implementation
+** does not have to do anything special based with the value of bPurgeable;
+** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
+** never invoke xUnpin() except to deliberately delete a page.
+** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
+** false will always have the "discard" flag set to true.  
+** ^Hence, a cache created with bPurgeable false will
+** never contain any unpinned pages.
+**
+** [[the xCachesize() page cache method]]
+** ^(The xCachesize() method may be called at any time by SQLite to set the
+** suggested maximum cache-size (number of pages stored by) the cache
+** instance passed as the first argument. This is the value configured using
+** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
+** parameter, the implementation is not required to do anything with this
+** value; it is advisory only.
+**
+** [[the xPagecount() page cache methods]]
+** The xPagecount() method must return the number of pages currently
+** stored in the cache, both pinned and unpinned.
+** 
+** [[the xFetch() page cache methods]]
+** The xFetch() method locates a page in the cache and returns a pointer to 
+** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
+** The pBuf element of the returned sqlite3_pcache_page object will be a
+** pointer to a buffer of szPage bytes used to store the content of a 
+** single database page.  The pExtra element of sqlite3_pcache_page will be
+** a pointer to the szExtra bytes of extra storage that SQLite has requested
+** for each entry in the page cache.
+**
+** The page to be fetched is determined by the key. ^The minimum key value
+** is 1.  After it has been retrieved using xFetch, the page is considered
+** to be "pinned".
+**
+** If the requested page is already in the page cache, then the page cache
+** implementation must return a pointer to the page buffer with its content
+** intact.  If the requested page is not already in the cache, then the
+** cache implementation should use the value of the createFlag
+** parameter to help it determined what action to take:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behavior when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+**                 Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
+**                 NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
+** will only use a createFlag of 2 after a prior call with a createFlag of 1
+** failed.)^  In between the xFetch() calls, SQLite may
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache.
+**
+** [[the xUnpin() page cache method]]
+** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
+** as its second argument.  If the third parameter, discard, is non-zero,
+** then the page must be evicted from the cache.
+** ^If the discard parameter is
+** zero, then the page may be discarded or retained at the discretion of
+** page cache implementation. ^The page cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache must not perform any reference counting. A single 
+** call to xUnpin() unpins the page regardless of the number of prior calls 
+** to xFetch().
+**
+** [[the xRekey() page cache methods]]
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument. If the cache
+** previously contains an entry associated with newKey, it must be
+** discarded. ^Any prior cache entry associated with newKey is guaranteed not
+** to be pinned.
+**
+** When SQLite calls the xTruncate() method, the cache must discard all
+** existing cache entries with page numbers (keys) greater than or equal
+** to the value of the iLimit parameter passed to xTruncate(). If any
+** of these pages are pinned, they are implicitly unpinned, meaning that
+** they can be safely discarded.
+**
+** [[the xDestroy() page cache method]]
+** ^The xDestroy() method is used to delete a cache allocated by xCreate().
+** All resources associated with the specified cache should be freed. ^After
+** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
+** handle invalid, and will not use it with any other sqlite3_pcache_methods2
+** functions.
+**
+** [[the xShrink() page cache method]]
+** ^SQLite invokes the xShrink() method when it wants the page cache to
+** free up as much of heap memory as possible.  The page cache implementation
+** is not obligated to free any memory, but well-behaved implementations should
+** do their best.

+** CAPI3REF: Unlock Notification
+** METHOD: sqlite3
+**
+** ^When running in shared-cache mode, a database operation may fail with
+** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
+** individual tables within the shared-cache cannot be obtained. See
+** [SQLite Shared-Cache Mode] for a description of shared-cache locking. 
+** ^This API may be used to register a callback that SQLite will invoke 
+** when the connection currently holding the required lock relinquishes it.
+** ^This API is only available if the library was compiled with the
+** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
+**
+** See Also: [Using the SQLite Unlock Notification Feature].
+**
+** ^Shared-cache locks are released when a database connection concludes
+** its current transaction, either by committing it or rolling it back. 
+**
+** ^When a connection (known as the blocked connection) fails to obtain a
+** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
+** identity of the database connection (the blocking connection) that
+** has locked the required resource is stored internally. ^After an 
+** application receives an SQLITE_LOCKED error, it may call the
+** sqlite3_unlock_notify() method with the blocked connection handle as 
+** the first argument to register for a callback that will be invoked
+** when the blocking connections current transaction is concluded. ^The
+** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
+** call that concludes the blocking connection's transaction.
+**
+** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
+** there is a chance that the blocking connection will have already
+** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
+** If this happens, then the specified callback is invoked immediately,
+** from within the call to sqlite3_unlock_notify().)^
+**
+** ^If the blocked connection is attempting to obtain a write-lock on a
+** shared-cache table, and more than one other connection currently holds
+** a read-lock on the same table, then SQLite arbitrarily selects one of 
+** the other connections to use as the blocking connection.
+**
+** ^(There may be at most one unlock-notify callback registered by a 
+** blocked connection. If sqlite3_unlock_notify() is called when the
+** blocked connection already has a registered unlock-notify callback,
+** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
+** called with a NULL pointer as its second argument, then any existing
+** unlock-notify callback is canceled. ^The blocked connections 
+** unlock-notify callback may also be canceled by closing the blocked
+** connection using [sqlite3_close()].
+**
+** The unlock-notify callback is not reentrant. If an application invokes
+** any sqlite3_xxx API functions from within an unlock-notify callback, a
+** crash or deadlock may be the result.
+**
+** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
+** returns SQLITE_OK.
+**
+** <b>Callback Invocation Details</b>
+**
+** When an unlock-notify callback is registered, the application provides a 
+** single void* pointer that is passed to the callback when it is invoked.
+** However, the signature of the callback function allows SQLite to pass
+** it an array of void* context pointers. The first argument passed to
+** an unlock-notify callback is a pointer to an array of void* pointers,
+** and the second is the number of entries in the array.
+**
+** When a blocking connection's transaction is concluded, there may be
+** more than one blocked connection that has registered for an unlock-notify
+** callback. ^If two or more such blocked connections have specified the
+** same callback function, then instead of invoking the callback function
+** multiple times, it is invoked once with the set of void* context pointers
+** specified by the blocked connections bundled together into an array.
+** This gives the application an opportunity to prioritize any actions 
+** related to the set of unblocked database connections.
+**
+** <b>Deadlock Detection</b>
+**
+** Assuming that after registering for an unlock-notify callback a 
+** database waits for the callback to be issued before taking any further
+** action (a reasonable assumption), then using this API may cause the
+** application to deadlock. For example, if connection X is waiting for
+** connection Y's transaction to be concluded, and similarly connection
+** Y is waiting on connection X's transaction, then neither connection
+** will proceed and the system may remain deadlocked indefinitely.
+**
+** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
+** detection. ^If a given call to sqlite3_unlock_notify() would put the
+** system in a deadlocked state, then SQLITE_LOCKED is returned and no
+** unlock-notify callback is registered. The system is said to be in
+** a deadlocked state if connection A has registered for an unlock-notify
+** callback on the conclusion of connection B's transaction, and connection
+** B has itself registered for an unlock-notify callback when connection
+** A's transaction is concluded. ^Indirect deadlock is also detected, so
+** the system is also considered to be deadlocked if connection B has
+** registered for an unlock-notify callback on the conclusion of connection
+** C's transaction, where connection C is waiting on connection A. ^Any
+** number of levels of indirection are allowed.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost 
+** always appropriate to call sqlite3_unlock_notify(). There is however,
+** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
+** SQLite checks if there are any currently executing SELECT statements
+** that belong to the same connection. If there are, SQLITE_LOCKED is
+** returned. In this case there is no "blocking connection", so invoking
+** sqlite3_unlock_notify() results in the unlock-notify callback being
+** invoked immediately. If the application then re-attempts the "DROP TABLE"
+** or "DROP INDEX" query, an infinite loop might be the result.
+**
+** One way around this problem is to check the extended error code returned
+** by an sqlite3_step() call. ^(If there is a blocking connection, then the
+** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
+** the special "DROP TABLE/INDEX" case, the extended error code is just 
+** SQLITE_LOCKED.)^

+** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are

+** are recorded for rows for which (idx IS NULL) is true. However, for such
+** rows a zero-length blob (SQL value X'') is stored in the changeset or
+** patchset instead of a NULL value. This allows such changesets to be
+** manipulated by legacy implementations of sqlite3changeset_invert(),
+** concat() and similar.
+**
+** The sqlite3changeset_apply() function automatically converts the 
+** zero-length blob back to a NULL value when updating the sqlite_stat1
+** table. However, if the application calls sqlite3changeset_new(),
+** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset 
+** iterator directly (including on a changeset iterator passed to a
+** conflict-handler callback) then the X'' value is returned. The application
+** must translate X'' to NULL itself if required.
+**
+** Legacy (older than 3.22.0) versions of the sessions module cannot capture
+** changes made to the sqlite_stat1 table. Legacy versions of the

+** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+** no corresponding change is present in the changesets returned by this
+** function. If an existing row with one or more NULL values stored in
+** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+** only an INSERT is appears in the changeset. Similarly, if an existing row
+** with non-NULL PRIMARY KEY values is updated so that one or more of its
+** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+** DELETE change only.
+**
+** The contents of a changeset may be traversed using an iterator created
+** using the [sqlite3changeset_start()] API. A changeset may be applied to
+** a database with a compatible schema using the [sqlite3changeset_apply()]
+** API.
+**
+** Within a changeset generated by this function, all changes related to a
+** single table are grouped together. In other words, when iterating through
+** a changeset or when applying a changeset to a database, all changes related
+** to a single table are processed before moving on to the next table. Tables
+** are sorted in the same order in which they were attached (or auto-attached)
+** to the sqlite3_session object. The order in which the changes related to
+** a single table are stored is undefined.
+**
+** Following a successful call to this function, it is the responsibility of
+** the caller to eventually free the buffer that *ppChangeset points to using
+** [sqlite3_free()].
+**
+** <h3>Changeset Generation</h3>
+**
+** Once a table has been attached to a session object, the session object
+** records the primary key values of all new rows inserted into the table.
+** It also records the original primary key and other column values of any
+** deleted or updated rows. For each unique primary key value, data is only
+** recorded once - the first time a row with said primary key is inserted,
+** updated or deleted in the lifetime of the session.
+**
+** There is one exception to the previous paragraph: when a row is inserted,
+** updated or deleted, if one or more of its primary key columns contain a
+** NULL value, no record of the change is made.
+**
+** The session object therefore accumulates two types of records - those
+** that consist of primary key values only (created when the user inserts
+** a new record) and those that consist of the primary key values and the
+** original values of other table columns (created when the users deletes
+** or updates a record).
+**
+** When this function is called, the requested changeset is created using
+** both the accumulated records and the current contents of the database
+** file. Specifically:
+**
+** <ul>
+**   <li> For each record generated by an insert, the database is queried
+**        for a row with a matching primary key. If one is found, an INSERT
+**        change is added to the changeset. If no such row is found, no change 
+**        is added to the changeset.
+**
+**   <li> For each record generated by an update or delete, the database is 
+**        queried for a row with a matching primary key. If such a row is
+**        found and one or more of the non-primary key fields have been
+**        modified from their original values, an UPDATE change is added to 
+**        the changeset. Or, if no such row is found in the table, a DELETE 
+**        change is added to the changeset. If there is a row with a matching
+**        primary key in the database, but all fields contain their original
+**        values, no change is added to the changeset.
+** </ul>
+**
+** This means, amongst other things, that if a row is inserted and then later
+** deleted while a session object is active, neither the insert nor the delete
+** will be present in the changeset. Or if a row is deleted and then later a 
+** row with the same primary key values inserted while a session object is
+** active, the resulting changeset will contain an UPDATE change instead of
+** a DELETE and an INSERT.
+**
+** When a session object is disabled (see the [sqlite3session_enable()] API),
+** it does not accumulate records when rows are inserted, updated or deleted.
+** This may appear to have some counter-intuitive effects if a single row
+** is written to more than once during a session. For example, if a row
+** is inserted while a session object is enabled, then later deleted while 
+** the same session object is disabled, no INSERT record will appear in the
+** changeset, even though the delete took place while the session was disabled.
+** Or, if one field of a row is updated while a session is disabled, and 
+** another field of the same row is updated while the session is enabled, the
+** resulting changeset will contain an UPDATE change that updates both fields.

+** used to update the table in database zFrom (call this the "from-table")

+** An sqlite3_changegroup object is used to combine two or more changesets

+** sqlite3changegroup_delete(). If an error occurs, an SQLite error code
+** (i.e. SQLITE_NOMEM) is returned and *pp is set to NULL.
+**
+** The usual usage pattern for an sqlite3_changegroup object is as follows:
+**
+** <ul>
+**   <li> It is created using a call to sqlite3changegroup_new().
+**
+**   <li> Zero or more changesets (or patchsets) are added to the object

+**   <li> The result of combining all input changesets together is obtained 
+**        by the application via a call to sqlite3changegroup_output().
+**
+**   <li> The object is deleted using a call to sqlite3changegroup_delete().
+** </ul>
+**
+** Any number of calls to add() and output() may be made between the calls to
+** new() and delete(), and in any order.
+**

+** Rows within the changeset and changegroup are identified by the values in

+** apply to the same row as a change already present in the changegroup if
+** the two rows have the same primary key.
+**
+** Changes to rows that do not already appear in the changegroup are
+** simply copied into it. Or, if both the new changeset and the changegroup

+**   <tr><td>INSERT <td>UPDATE <td>
+**       The INSERT change remains in the changegroup. The values in the 
+**       INSERT change are modified as if the row was inserted by the
+**       existing change and then updated according to the new change.

+**       The new change is ignored. This case does not occur if the new
+**       changeset was recorded immediately after the changesets already
+**       added to the changegroup.
+**   <tr><td>UPDATE <td>UPDATE <td>
+**       The existing UPDATE remains within the changegroup. It is amended 
+**       so that the accompanying values are as if the row was updated once 
+**       by the existing change and then again by the new change.
+**   <tr><td>UPDATE <td>DELETE <td>

+**       changegroup.
+**   <tr><td>DELETE <td>INSERT <td>
+**       If one or more of the column values in the row inserted by the

+**
+** Apply a changeset or patchset to a database. These functions attempt to

+** the changeset passed via the second and third arguments. 
+**
+** The fourth argument (xFilter) passed to these functions is the "filter
+** callback". If it is not NULL, then for each table affected by at least one
+** change in the changeset, the filter callback is invoked with
+** the table name as the second argument, and a copy of the context pointer
+** passed as the sixth argument as the first. If the "filter callback"
+** returns zero, then no attempt is made to apply any changes to the table.
+** Otherwise, if the return value is non-zero or the xFilter argument to
+** is NULL, all changes related to the table are attempted.
+**
+** For each table that is not excluded by the filter callback, this function 
+** tests that the target database contains a compatible table. A table is 
+** considered compatible if all of the following are true:
+**
+** <ul>
+**   <li> The table has the same name as the name recorded in the 
+**        changeset, and
+**   <li> The table has at least as many columns as recorded in the 
+**        changeset, and
+**   <li> The table has primary key columns in the same position as 
+**        recorded in the changeset.
+** </ul>
+**
+** If there is no compatible table, it is not an error, but none of the
+** changes associated with the table are applied. A warning message is issued
+** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
+** one such warning is issued for each table in the changeset.
+**
+** For each change for which there is a compatible table, an attempt is made 
+** to modify the table contents according to the UPDATE, INSERT or DELETE 
+** change. If a change cannot be applied cleanly, the conflict handler 
+** function passed as the fifth argument to sqlite3changeset_apply() may be 
+** invoked. A description of exactly when the conflict handler is invoked for 
+** each type of change is below.
+**
+** Unlike the xFilter argument, xConflict may not be passed NULL. The results
+** of passing anything other than a valid function pointer as the xConflict
+** argument are undefined.
+**
+** Each time the conflict handler function is invoked, it must return one
+** of [SQLITE_CHANGESET_OMIT], [SQLITE_CHANGESET_ABORT] or 
+** [SQLITE_CHANGESET_REPLACE]. SQLITE_CHANGESET_REPLACE may only be returned
+** if the second argument passed to the conflict handler is either
+** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
+** returns an illegal value, any changes already made are rolled back and
+** the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different 
+** actions are taken by sqlite3changeset_apply() depending on the value
+** returned by each invocation of the conflict-handler function. Refer to
+** the documentation for the three 
+** [SQLITE_CHANGESET_OMIT|available return values] for details.
+**
+** <dl>
+** <dt>DELETE Changes<dd>
+**   For each DELETE change, the function checks if the target database 
+**   contains a row with the same primary key value (or values) as the 
+**   original row values stored in the changeset. If it does, and the values 
+**   stored in all non-primary key columns also match the values stored in 
+**   the changeset the row is deleted from the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the non-primary key fields contains a value different from the original
+**   row value stored in the changeset, the conflict-handler function is
+**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
+**   database table has more columns than are recorded in the changeset,
+**   only the values of those non-primary key fields are compared against
+**   the current database contents - any trailing database table columns
+**   are ignored.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
+**   (which can only happen if a foreign key constraint is violated), the
+**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
+**   passed as the second argument. This includes the case where the DELETE
+**   operation is attempted because an earlier call to the conflict handler
+**   function returned [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>INSERT Changes<dd>
+**   For each INSERT change, an attempt is made to insert the new row into
+**   the database. If the changeset row contains fewer fields than the
+**   database table, the trailing fields are populated with their default
+**   values.
+**
+**   If the attempt to insert the row fails because the database already 
+**   contains a row with the same primary key values, the conflict handler
+**   function is invoked with the second argument set to 
+**   [SQLITE_CHANGESET_CONFLICT].
+**
+**   If the attempt to insert the row fails because of some other constraint
+**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is 
+**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
+**   This includes the case where the INSERT operation is re-attempted because 
+**   an earlier call to the conflict handler function returned 
+**   [SQLITE_CHANGESET_REPLACE].
+**
+** <dt>UPDATE Changes<dd>
+**   For each UPDATE change, the function checks if the target database 
+**   contains a row with the same primary key value (or values) as the 
+**   original row values stored in the changeset. If it does, and the values 
+**   stored in all modified non-primary key columns also match the values
+**   stored in the changeset the row is updated within the target database.
+**
+**   If a row with matching primary key values is found, but one or more of
+**   the modified non-primary key fields contains a value different from an
+**   original row value stored in the changeset, the conflict-handler function
+**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
+**   UPDATE changes only contain values for non-primary key fields that are
+**   to be modified, only those fields need to match the original values to
+**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
+**
+**   If no row with matching primary key values is found in the database,
+**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
+**   passed as the second argument.
+**
+**   If the UPDATE operation is attempted, but SQLite returns 
+**   SQLITE_CONSTRAINT, the conflict-handler function is invoked with 
+**   [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
+**   This includes the case where the UPDATE operation is attempted after 
+**   an earlier call to the conflict handler function returned
+**   [SQLITE_CHANGESET_REPLACE].

+**
+** It is safe to execute SQL statements, including those that write to the
+** table that the callback related to, from within the xConflict callback.
+** This can be used to further customize the application's conflict
+** resolution strategy.
+**
+** All changes made by these functions are enclosed in a savepoint transaction.
+** If any other error (aside from a constraint failure when attempting to
+** write to the target database) occurs, then the savepoint transaction is
+** rolled back, restoring the target database to its original state, and an 
+** SQLite error code returned.
+**
+** If the output parameters (ppRebase) and (pnRebase) are non-NULL and
+** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
+** may set (*ppRebase) to point to a "rebase" that may be used with the

+** Rebasing a changeset is to update it to take those conflict 
+** resolution decisions into account, so that the same conflicts
+** do not have to be resolved elsewhere in the network. 
+**
+** For example, if both the local and remote changesets contain an
+** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
+**
+**   local:  INSERT INTO t1 VALUES(1, 'v1');
+**   remote: INSERT INTO t1 VALUES(1, 'v2');
+**
+** and the conflict resolution is REPLACE, then the INSERT change is
+** removed from the local changeset (it was overridden). Or, if the
+** conflict resolution was "OMIT", then the local changeset is modified
+** to instead contain:
+**
+**           UPDATE t1 SET b = 'v2' WHERE a=1;
+**
+** Changes within the local changeset are rebased as follows:
+**
+** <dl>
+** <dt>Local INSERT<dd>
+**   This may only conflict with a remote INSERT. If the conflict 
+**   resolution was OMIT, then add an UPDATE change to the rebased
+**   changeset. Or, if the conflict resolution was REPLACE, add
+**   nothing to the rebased changeset.
+**
+** <dt>Local DELETE<dd>
+**   This may conflict with a remote UPDATE or DELETE. In both cases the
+**   only possible resolution is OMIT. If the remote operation was a
+**   DELETE, then add no change to the rebased changeset. If the remote
+**   operation was an UPDATE, then the old.* fields of change are updated
+**   to reflect the new.* values in the UPDATE.
+**
+** <dt>Local UPDATE<dd>
+**   This may conflict with a remote UPDATE or DELETE. If it conflicts
+**   with a DELETE, and the conflict resolution was OMIT, then the update
+**   is changed into an INSERT. Any undefined values in the new.* record
+**   from the update change are filled in using the old.* values from
+**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+**   the UPDATE change is simply omitted from the rebased changeset.
+**
+**   If conflict is with a remote UPDATE and the resolution is OMIT, then
+**   the old.* values are rebased using the new.* values in the remote
+**   change. Or, if the resolution is REPLACE, then the change is copied
+**   into the rebased changeset with updates to columns also updated by
+**   the conflicting remote UPDATE removed. If this means no columns would 
+**   be updated, the change is omitted.
+** </dl>
+**
+** A local change may be rebased against multiple remote changes 
+** simultaneously. If a single key is modified by multiple remote 
+** changesets, they are combined as follows before the local changeset
+** is rebased:
+**
+** <ul>
+**    <li> If there has been one or more REPLACE resolutions on a
+**         key, it is rebased according to a REPLACE.
+**
+**    <li> If there have been no REPLACE resolutions on a key, then
+**         the local changeset is rebased according to the most recent
+**         of the OMIT resolutions.
+** </ul>
+**
+** Note that conflict resolutions from multiple remote changesets are 
+** combined on a per-field basis, not per-row. This means that in the 
+** case of multiple remote UPDATE operations, some fields of a single 
+** local change may be rebased for REPLACE while others are rebased for 
+** OMIT.
+**
+** In order to rebase a local changeset, the remote changeset must first
+** be applied to the local database using sqlite3changeset_apply_v2() and
+** the buffer of rebase information captured. Then:
+**
+** <ol>
+**   <li> An sqlite3_rebaser object is created by calling 
+**        sqlite3rebaser_create().
+**   <li> The new object is configured with the rebase buffer obtained from
+**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+**        If the local changeset is to be rebased against multiple remote
+**        changesets, then sqlite3rebaser_configure() should be called
+**        multiple times, in the same order that the multiple
+**        sqlite3changeset_apply_v2() calls were made.
+**   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().
+**   <li> The sqlite3_rebaser object is deleted by calling
+**        sqlite3rebaser_delete().

+**
+** Non-streaming functions that accept changesets (or patchsets) as input
+** require that the entire changeset be stored in a single buffer in memory. 
+** Similarly, those that return a changeset or patchset do so by returning 
+** a pointer to a single large buffer allocated using sqlite3_malloc(). 
+** Normally this is convenient. However, if an application running in a 
+** low-memory environment is required to handle very large changesets, the
+** large contiguous memory allocations required can become onerous.
+**
+** In order to avoid this problem, instead of a single large buffer, input
+** is passed to a streaming API functions by way of a callback function that
+** the sessions module invokes to incrementally request input data as it is
+** required. In all cases, a pair of API function parameters such as
+**
+**  <pre>
+**  &nbsp;     int nChangeset,
+**  &nbsp;     void *pChangeset,
+**  </pre>
+**
+** Is replaced by:
+**
+**  <pre>
+**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+**  &nbsp;     void *pIn,
+**  </pre>
+**
+** Each time the xInput callback is invoked by the sessions module, the first
+** argument passed is a copy of the supplied pIn context pointer. The second 
+** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no 
+** error occurs the xInput method should copy up to (*pnData) bytes of data 
+** into the buffer and set (*pnData) to the actual number of bytes copied 
+** before returning SQLITE_OK. If the input is completely exhausted, (*pnData) 
+** should be set to zero to indicate this. Or, if an error occurs, an SQLite 
+** error code should be returned. In all cases, if an xInput callback returns
+** an error, all processing is abandoned and the streaming API function
+** returns a copy of the error code to the caller.
+**
+** In the case of sqlite3changeset_start_strm(), the xInput callback may be
+** invoked by the sessions module at any point during the lifetime of the
+** iterator. If such an xInput callback returns an error, the iterator enters
+** an error state, whereby all subsequent calls to iterator functions 
+** immediately fail with the same error code as returned by xInput.
+**
+** Similarly, streaming API functions that return changesets (or patchsets)
+** return them in chunks by way of a callback function instead of via a
+** pointer to a single large buffer. In this case, a pair of parameters such
+** as:
+**
+**  <pre>
+**  &nbsp;     int *pnChangeset,
+**  &nbsp;     void **ppChangeset,
+**  </pre>
+**
+** Is replaced by:
+**
+**  <pre>
+**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+**  &nbsp;     void *pOut
+**  </pre>
+**
+** The xOutput callback is invoked zero or more times to return data to
+** the application. The first parameter passed to each call is a copy of the
+** pOut pointer supplied by the application. The second parameter, pData,
+** points to a buffer nData bytes in size containing the chunk of output
+** data being returned. If the xOutput callback successfully processes the
+** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
+** it should return some other SQLite error code. In this case processing
+** is immediately abandoned and the streaming API function returns a copy
+** of the xOutput error code to the application.
+**
+** The sessions module never invokes an xOutput callback with the third 
+** parameter set to a value less than or equal to zero. Other than this,
+** no guarantees are made as to the size of the chunks of data returned.

+** EXTENSION API FUNCTIONS
+**
+** xUserData(pFts):
+**   Return a copy of the context pointer the extension function was 
+**   registered with.
+**
+** xColumnTotalSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the FTS5 table. Or, if iCol is
+**   non-negative but less than the number of columns in the table, return
+**   the total number of tokens in column iCol, considering all rows in 
+**   the FTS5 table.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is 
+**   returned.
+**
+** xColumnCount(pFts):
+**   Return the number of columns in the table.
+**
+** xColumnSize(pFts, iCol, pnToken):
+**   If parameter iCol is less than zero, set output variable *pnToken
+**   to the total number of tokens in the current row. Or, if iCol is
+**   non-negative but less than the number of columns in the table, set
+**   *pnToken to the number of tokens in column iCol of the current row.
+**
+**   If parameter iCol is greater than or equal to the number of columns
+**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
+**   an OOM condition or IO error), an appropriate SQLite error code is 
+**   returned.
+**
+**   This function may be quite inefficient if used with an FTS5 table
+**   created with the "columnsize=0" option.
+**
+** xColumnText:
+**   This function attempts to retrieve the text of column iCol of the
+**   current document. If successful, (*pz) is set to point to a buffer
+**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
+**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
+**   if an error occurs, an SQLite error code is returned and the final values
+**   of (*pz) and (*pn) are undefined.
+**
+** xPhraseCount:
+**   Returns the number of phrases in the current query expression.
+**
+** xPhraseSize:
+**   Returns the number of tokens in phrase iPhrase of the query. Phrases
+**   are numbered starting from zero.
+**
+** xInstCount:
+**   Set *pnInst to the total number of occurrences of all phrases within
+**   the query within the current row. Return SQLITE_OK if successful, or
+**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created 
+**   with either "detail=none" or "detail=column" and "content=" option 
+**   (i.e. if it is a contentless table), then this API always returns 0.
+**
+** xInst:
+**   Query for the details of phrase match iIdx within the current row.
+**   Phrase matches are numbered starting from zero, so the iIdx argument
+**   should be greater than or equal to zero and smaller than the value
+**   output by xInstCount().
+**
+**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
+**   to the column in which it occurs and *piOff the token offset of the
+**   first token of the phrase. Returns SQLITE_OK if successful, or an error
+**   code (i.e. SQLITE_NOMEM) if an error occurs.
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. 
+**
+** xRowid:
+**   Returns the rowid of the current row.
+**
+** xTokenize:
+**   Tokenize text using the tokenizer belonging to the FTS5 table.
+**
+** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
+**   This API function is used to query the FTS table for phrase iPhrase
+**   of the current query. Specifically, a query equivalent to:
+**
+**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
+**
+**   with $p set to a phrase equivalent to the phrase iPhrase of the
+**   current query is executed. Any column filter that applies to
+**   phrase iPhrase of the current query is included in $p. For each 
+**   row visited, the callback function passed as the fourth argument 
+**   is invoked. The context and API objects passed to the callback 
+**   function may be used to access the properties of each matched row.
+**   Invoking Api.xUserData() returns a copy of the pointer passed as 
+**   the third argument to pUserData.
+**
+**   If the callback function returns any value other than SQLITE_OK, the
+**   query is abandoned and the xQueryPhrase function returns immediately.
+**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
+**   Otherwise, the error code is propagated upwards.
+**
+**   If the query runs to completion without incident, SQLITE_OK is returned.
+**   Or, if some error occurs before the query completes or is aborted by
+**   the callback, an SQLite error code is returned.
+**
+**
+** xSetAuxdata(pFts5, pAux, xDelete)
+**
+**   Save the pointer passed as the second argument as the extension function's 
+**   "auxiliary data". The pointer may then be retrieved by the current or any
+**   future invocation of the same fts5 extension function made as part of
+**   the same MATCH query using the xGetAuxdata() API.
+**
+**   Each extension function is allocated a single auxiliary data slot for
+**   each FTS query (MATCH expression). If the extension function is invoked 
+**   more than once for a single FTS query, then all invocations share a 
+**   single auxiliary data context.
+**
+**   If there is already an auxiliary data pointer when this function is
+**   invoked, then it is replaced by the new pointer. If an xDelete callback
+**   was specified along with the original pointer, it is invoked at this
+**   point.
+**
+**   The xDelete callback, if one is specified, is also invoked on the
+**   auxiliary data pointer after the FTS5 query has finished.
+**
+**   If an error (e.g. an OOM condition) occurs within this function,
+**   the auxiliary data is set to NULL and an error code returned. If the
+**   xDelete parameter was not NULL, it is invoked on the auxiliary data
+**   pointer before returning.
+**
+**
+** xGetAuxdata(pFts5, bClear)
+**
+**   Returns the current auxiliary data pointer for the fts5 extension 
+**   function. See the xSetAuxdata() method for details.
+**
+**   If the bClear argument is non-zero, then the auxiliary data is cleared
+**   (set to NULL) before this function returns. In this case the xDelete,
+**   if any, is not invoked.
+**
+**
+** xRowCount(pFts5, pnRow)
+**
+**   This function is used to retrieve the total number of rows in the table.
+**   In other words, the same value that would be returned by:
+**
+**        SELECT count(*) FROM ftstable;
+**
+** xPhraseFirst()
+**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
+**   method, to iterate through all instances of a single query phrase within
+**   the current row. This is the same information as is accessible via the
+**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
+**   to use, this API may be faster under some circumstances. To iterate 
+**   through instances of phrase iPhrase, use the following code:
+**
+**       Fts5PhraseIter iter;
+**       int iCol, iOff;
+**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
+**           iCol>=0;
+**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
+**       ){
+**         // An instance of phrase iPhrase at offset iOff of column iCol
+**       }
+**
+**   The Fts5PhraseIter structure is defined above. Applications should not
+**   modify this structure directly - it should only be used as shown above
+**   with the xPhraseFirst() and xPhraseNext() API methods (and by
+**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" or "detail=column" option. If the FTS5 table is created 
+**   with either "detail=none" or "detail=column" and "content=" option 
+**   (i.e. if it is a contentless table), then this API always iterates
+**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
+**
+** xPhraseNext()
+**   See xPhraseFirst above.
+**
+** xPhraseFirstColumn()
+**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
+**   and xPhraseNext() APIs described above. The difference is that instead
+**   of iterating through all instances of a phrase in the current row, these
+**   APIs are used to iterate through the set of columns in the current row
+**   that contain one or more instances of a specified phrase. For example:
+**
+**       Fts5PhraseIter iter;
+**       int iCol;
+**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
+**           iCol>=0;
+**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
+**       ){
+**         // Column iCol contains at least one instance of phrase iPhrase
+**       }
+**
+**   This API can be quite slow if used with an FTS5 table created with the
+**   "detail=none" option. If the FTS5 table is created with either 
+**   "detail=none" "content=" option (i.e. if it is a contentless table), 
+**   then this API always iterates through an empty set (all calls to 
+**   xPhraseFirstColumn() set iCol to -1).
+**
+**   The information accessed using this API and its companion
+**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
+**   (or xInst/xInstCount). The chief advantage of this API is that it is
+**   significantly more efficient than those alternatives when used with
+**   "detail=column" tables.  
+**
+** xPhraseNextColumn()

+** CUSTOM AUXILIARY FUNCTIONS
+*************************************************************************/
+
+/*************************************************************************
+** CUSTOM TOKENIZERS
+**
+** Applications may also register custom tokenizer types. A tokenizer 
+** is registered by providing fts5 with a populated instance of the 
+** following structure. All structure methods must be defined, setting
+** any member of the fts5_tokenizer struct to NULL leads to undefined
+** behaviour. The structure methods are expected to function as follows:
+**
+** xCreate:
+**   This function is used to allocate and initialize a tokenizer instance.
+**   A tokenizer instance is required to actually tokenize text.
+**
+**   The first argument passed to this function is a copy of the (void*)
+**   pointer provided by the application when the fts5_tokenizer object
+**   was registered with FTS5 (the third argument to xCreateTokenizer()). 
+**   The second and third arguments are an array of nul-terminated strings
+**   containing the tokenizer arguments, if any, specified following the
+**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
+**   to create the FTS5 table.
+**
+**   The final argument is an output variable. If successful, (*ppOut) 
+**   should be set to point to the new tokenizer handle and SQLITE_OK
+**   returned. If an error occurs, some value other than SQLITE_OK should
+**   be returned. In this case, fts5 assumes that the final value of *ppOut 
+**   is undefined.
+**
+** xDelete:
+**   This function is invoked to delete a tokenizer handle previously
+**   allocated using xCreate(). Fts5 guarantees that this function will
+**   be invoked exactly once for each successful call to xCreate().
+**
+** xTokenize:
+**   This function is expected to tokenize the nText byte string indicated 
+**   by argument pText. pText may or may not be nul-terminated. The first
+**   argument passed to this function is a pointer to an Fts5Tokenizer object
+**   returned by an earlier call to xCreate().
+**
+**   The second argument indicates the reason that FTS5 is requesting
+**   tokenization of the supplied text. This is always one of the following
+**   four values:
+**
+**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
+**            or removed from the FTS table. The tokenizer is being invoked to
+**            determine the set of tokens to add to (or delete from) the
+**            FTS index.
+**
+**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed 
+**            against the FTS index. The tokenizer is being called to tokenize 
+**            a bareword or quoted string specified as part of the query.
+**
+**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
+**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
+**            followed by a "*" character, indicating that the last token
+**            returned by the tokenizer will be treated as a token prefix.
+**
+**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to 
+**            satisfy an fts5_api.xTokenize() request made by an auxiliary
+**            function. Or an fts5_api.xColumnSize() request made by the same
+**            on a columnsize=0 database.  
+**   </ul>
+**
+**   For each token in the input string, the supplied callback xToken() must
+**   be invoked. The first argument to it should be a copy of the pointer
+**   passed as the second argument to xTokenize(). The third and fourth
+**   arguments are a pointer to a buffer containing the token text, and the
+**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
+**   of the first byte of and first byte immediately following the text from
+**   which the token is derived within the input.
+**
+**   The second argument passed to the xToken() callback ("tflags") should
+**   normally be set to 0. The exception is if the tokenizer supports 
+**   synonyms. In this case see the discussion below for details.
+**
+**   FTS5 assumes the xToken() callback is invoked for each token in the 
+**   order that they occur within the input text.
+**
+**   If an xToken() callback returns any value other than SQLITE_OK, then
+**   the tokenization should be abandoned and the xTokenize() method should
+**   immediately return a copy of the xToken() return value. Or, if the
+**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
+**   if an error occurs with the xTokenize() implementation itself, it
+**   may abandon the tokenization and return any error code other than
+**   SQLITE_OK or SQLITE_DONE.
+**
+** SYNONYM SUPPORT
+**
+**   Custom tokenizers may also support synonyms. Consider a case in which a
+**   user wishes to query for a phrase such as "first place". Using the 
+**   built-in tokenizers, the FTS5 query 'first + place' will match instances
+**   of "first place" within the document set, but not alternative forms
+**   such as "1st place". In some applications, it would be better to match
+**   all instances of "first place" or "1st place" regardless of which form
+**   the user specified in the MATCH query text.
+**
+**   There are several ways to approach this in FTS5:
+**
+**   <ol><li> By mapping all synonyms to a single token. In this case, using
+**            the above example, this means that the tokenizer returns the
+**            same token for inputs "first" and "1st". Say that token is in
+**            fact "first", so that when the user inserts the document "I won
+**            1st place" entries are added to the index for tokens "i", "won",
+**            "first" and "place". If the user then queries for '1st + place',
+**            the tokenizer substitutes "first" for "1st" and the query works
+**            as expected.
+**
+**       <li> By querying the index for all synonyms of each query term
+**            separately. In this case, when tokenizing query text, the
+**            tokenizer may provide multiple synonyms for a single term 
+**            within the document. FTS5 then queries the index for each 
+**            synonym individually. For example, faced with the query:
+**
+**   <codeblock>
+**     ... MATCH 'first place'</codeblock>
+**
+**            the tokenizer offers both "1st" and "first" as synonyms for the
+**            first token in the MATCH query and FTS5 effectively runs a query 
+**            similar to:
+**
+**   <codeblock>
+**     ... MATCH '(first OR 1st) place'</codeblock>
+**
+**            except that, for the purposes of auxiliary functions, the query
+**            still appears to contain just two phrases - "(first OR 1st)" 
+**            being treated as a single phrase.
+**
+**       <li> By adding multiple synonyms for a single term to the FTS index.
+**            Using this method, when tokenizing document text, the tokenizer
+**            provides multiple synonyms for each token. So that when a 
+**            document such as "I won first place" is tokenized, entries are
+**            added to the FTS index for "i", "won", "first", "1st" and
+**            "place".
+**
+**            This way, even if the tokenizer does not provide synonyms
+**            when tokenizing query text (it should not - to do so would be
+**            inefficient), it doesn't matter if the user queries for 
+**            'first + place' or '1st + place', as there are entries in the
+**            FTS index corresponding to both forms of the first token.
+**   </ol>
+**
+**   Whether it is parsing document or query text, any call to xToken that
+**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
+**   is considered to supply a synonym for the previous token. For example,
+**   when parsing the document "I won first place", a tokenizer that supports
+**   synonyms would call xToken() 5 times, as follows:
+**
+**   <codeblock>
+**       xToken(pCtx, 0, "i",                      1,  0,  1);
+**       xToken(pCtx, 0, "won",                    3,  2,  5);
+**       xToken(pCtx, 0, "first",                  5,  6, 11);
+**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
+**       xToken(pCtx, 0, "place",                  5, 12, 17);
+**</codeblock>
+**
+**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
+**   xToken() is called. Multiple synonyms may be specified for a single token
+**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence. 
+**   There is no limit to the number of synonyms that may be provided for a
+**   single token.
+**
+**   In many cases, method (1) above is the best approach. It does not add 
+**   extra data to the FTS index or require FTS5 to query for multiple terms,
+**   so it is efficient in terms of disk space and query speed. However, it
+**   does not support prefix queries very well. If, as suggested above, the
+**   token "first" is substituted for "1st" by the tokenizer, then the query:
+**
+**   <codeblock>
+**     ... MATCH '1s*'</codeblock>
+**
+**   will not match documents that contain the token "1st" (as the tokenizer
+**   will probably not map "1s" to any prefix of "first").
+**
+**   For full prefix support, method (3) may be preferred. In this case, 
+**   because the index contains entries for both "first" and "1st", prefix
+**   queries such as 'fi*' or '1s*' will match correctly. However, because
+**   extra entries are added to the FTS index, this method uses more space
+**   within the database.
+**
+**   Method (2) offers a midpoint between (1) and (3). Using this method,
+**   a query such as '1s*' will match documents that contain the literal 
+**   token "1st", but not "first" (assuming the tokenizer is not able to
+**   provide synonyms for prefixes). However, a non-prefix query like '1st'
+**   will match against "1st" and "first". This method does not require
+**   extra disk space, as no extra entries are added to the FTS index. 
+**   On the other hand, it may require more CPU cycles to run MATCH queries,
+**   as separate queries of the FTS index are required for each synonym.
+**
+**   When using methods (2) or (3), it is important that the tokenizer only
+**   provide synonyms when tokenizing document text (method (2)) or query
+**   text (method (3)), not both. Doing so will not cause any errors, but is
+**   inefficient.

+## 0.3.0
+
+- Bump `package:native_assets_cli` to 0.3.0
+  ([#142](https://github.com/dart-lang/native/issues/142)).
+
+## 0.2.3
+
+- Quicker build planning for 0 or 1 packages with native assets
+  ([#128](https://github.com/dart-lang/native/issues/128)).
+
+## 0.2.2
+
+- Take a `PackageLayout` argument for `build` and `dryRun`
+  ([flutter#134427](https://github.com/flutter/flutter/issues/134427)).
+
+## 0.2.1
+
+- Provide a `PackageLayout` constructor for already parsed `PackageConfig`
+  ([flutter#134427](https://github.com/flutter/flutter/issues/134427)).
+
+## 0.2.0
+
+- **Breaking change** `NativeAssetsBuildRunner`s methods now return an object
+  ([#105](https://github.com/dart-lang/native/issues/105)).
+- **Breaking change** `NativeAssetsBuildRunner`s methods now return value now
+  contain a success bool instead of throwing
+  ([#106](https://github.com/dart-lang/native/issues/106)). Error messages are
+  streamed to the logger.
+- Use an `out/` sub directory for building native assets
+  ([#98](https://github.com/dart-lang/native/issues/98)).
+- Check asset ids on having having a package uri with the owning package
+  ([#96](https://github.com/dart-lang/native/issues/96)).
+- `NativeAssetsBuildRunner` now supports multiple calls
+  ([#102](https://github.com/dart-lang/native/issues/102)).
+
+## 0.1.0
+
+- Initial version.

+This package contains the shared logic for invoking [native assets CLI]s.
+
+## Audience
+
+This package is not intended for users, rather it is shared logic for Dart
+launchers to invoke the native assets CLIs of packages.
+Known Dart launchers using this shared logic: [dartdev] and [flutter_tools].
+
+For more information on how to use native assets as a user see 
+package [native assets CLI].

+
+This library contains the CLI specification and a default implementation
+for bundling native code with Dart packages.
+
+## Status: Experimental
+
+**NOTE**: This package is currently experimental and published under the
+[labs.dart.dev](https://dart.dev/dart-team-packages) pub publisher in order to
+solicit feedback. 
+
+For packages in the labs.dart.dev publisher we generally plan to either graduate
+the package into a supported publisher (dart.dev, tools.dart.dev) after a period
+of feedback and iteration, or discontinue the package. These packages have a
+much higher expected rate of API and breaking changes.
+
+Your feedback is valuable and will help us evolve this package. 
+For bugs, please file an issue in the 
+[bug tracker](https://github.com/dart-lang/native/issues).
+For general feedback and suggestions for the native assets feature in Dart and
+Flutter, please comment in [dart-lang#50565] or [flutter#129757].
+
+## Example
+
+A typical layout of a package with native code is:
+
+* `lib/` contains Dart code which uses [`dart:ffi`] and [`package:ffigen`]
+  to call into native code.
+* `src/` contains C/C++/Rust code which is invoked through `dart:ffi`.
+* `build.dart` implements the CLI that communicates which native assets
+  to build/bundle with the Dart/Flutter SDK. This file uses the
+  protocol specified in this package.
+
+An example can be found in [example/](example/).
+
+## Usage
+
+Using the native assets feature requires passing
+`--enable-experiment=native-assets` in Dart on a dev build.
+
+The native assets feature is not yet available in Flutter.
+
+## Development
+
+The development of the feature can be tracked in [dart-lang#50565],
+[flutter#129757], and in the issue tracker on this repository.

+
+## Status: Experimental
+
+**NOTE**: This package is currently experimental and published under the
+[labs.dart.dev](https://dart.dev/dart-team-packages) pub publisher in order to
+solicit feedback. 
+
+For packages in the labs.dart.dev publisher we generally plan to either graduate
+the package into a supported publisher (dart.dev, tools.dart.dev) after a period
+of feedback and iteration, or discontinue the package. These packages have a
+much higher expected rate of API and breaking changes.
+
+Your feedback is valuable and will help us evolve this package. 
+For bugs, please file an issue in the 
+[bug tracker](https://github.com/dart-lang/native/issues).
+
+
+## Example
+
+An example can be found in [../native_assets_cli/example/](../native_assets_cli/example/).
