  /// to the parser, which recognizes this token and determines, based on the

  /// 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

  /// 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 ">",

  /// 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
