58	*
59	* The C Interface to Clang provides a relatively small API that exposes
60	* facilities for parsing source code into an abstract syntax tree (AST),
61	* loading already-parsed ASTs, traversing the AST, associating
62	* physical source locations with elements within the AST, and other
63	* facilities that support Clang-based development tools.
64	*
65	* This C interface to Clang will never provide all of the information
66	* representation stored in Clang's C++ AST, nor should it: the intent is to
67	* maintain an API that is relatively stable from one release to the next,
68	* providing only the basic functionality needed to support development tools.
69	*
70	* To avoid namespace pollution, data types are prefixed with "CX" and
71	* functions are prefixed with "clang_".

2756	* In both Objective-C and C++, a method (aka virtual member function,

2763	* implementation is considered to override the same methods as its
2764	* corresponding method in the interface.
2765	*
2766	* For C++, a virtual member function overrides any virtual member
2767	* function with the same signature that occurs in its base
2768	* classes. With multiple inheritance, a virtual member function can
2769	* override several virtual member functions coming from different
2770	* base classes.
2771	*
2772	* In all cases, this function determines the immediate overridden
2773	* method, rather than all of the overridden methods. For example, if
2774	* a method is originally declared in a class A, then overridden in B
2775	* (which in inherits from A) and also in C (which inherited from B),

5656	* This function performs code completion at a particular file, line, and
5657	* column within source code, providing results that suggest potential
5658	* code snippets based on the context of the completion. The basic model
5659	* for code completion is that Clang will parse a complete source file,
5660	* performing syntax checking up to the location where code-completion has
5661	* been requested. At that point, a special code-completion token is passed
5662	* to the parser, which recognizes this token and determines, based on the
5663	* current location in the C/Objective-C/C++ grammar and the state of
5664	* semantic analysis, what completions to provide. These completions are
5665	* returned via a new \c CXCodeCompleteResults structure.
5666	*
5667	* Code completion itself is meant to be triggered by the client when the
5668	* user types punctuation characters or whitespace, at which point the
5669	* code-completion location will coincide with the cursor. For example, if \c p
5670	* is a pointer, code-completion might be triggered after the "-" and then
5671	* after the ">" in \c p->. When the code-completion location is after the ">",
5672	* the completion results will provide, e.g., the members of the struct that
5673	* "p" points to. The client is responsible for placing the cursor at the
5674	* beginning of the token currently being typed, then filtering the results
5675	* based on the contents of the token. For example, when code-completing for
5676	* the expression \c p->get, the client should provide the location just after
5677	* the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
5678	* client can filter the results based on the current token text ("get"), only
5679	* showing those results that start with "get". The intent of this interface
5680	* is to separate the relatively high-latency acquisition of code-completion
5681	* results from the filtering of results on a per-character basis, which must

5687	* be overridden via \p unsaved_files). Cursors referring into the
5688	* translation unit may be invalidated by this invocation.
5689	*
5690	* \param complete_filename The name of the source file where code
5691	* completion should be performed. This filename may be any file

5700	* \param unsaved_files the Files that have not yet been saved to disk
5701	* but may be required for parsing or code completion, including the
