* A VM status callback. Status plug-ins implement and register this
* function using Dart_RegisterStatusPlugin. When Dart_GetVMStatus is
* called, each callback is invoked to provide the requested information,
* and the first one to do so "wins".
* Note: status requests execute outside of an isolate (which is why
* handles aren't used).
* \param request an optional string that defines REST-like parameters
* to define what information is requested.
* \return Returns a valid JSON string, allocated from C heap. The caller
* is responsible for releasing this string. NULL is returned if the
* callback didn't handle that request.
typedef char* (*Dart_VmStatusCallback)(const char* request);
* Register a VM status plug-in. The specified status type must not already
* have a registered plug-in.
* \return 0 if the plug-in was registered, or -1 if there is an error.
