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

* 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.

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

* after the ">" in \c p->. When the code-completion location is afer 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
* have a lower latency.
*
* \param TU The translation unit in which code-completion should
* occur. The source files for this translation unit need not be
* completely up-to-date (and the contents of those source files may
* be overridden via \p unsaved_files). Cursors referring into the
* translation unit may be invalidated by this invocation.
*
* \param complete_filename The name of the source file where code
* completion should be performed. This filename may be any file
* included in the translation unit.
*
* \param complete_line The line at which code-completion should occur.
*
* \param complete_column The column at which code-completion should occur.
* Note that the column should point just after the syntactic construct that
* initiated code completion, and not in the middle of a lexical token.
*
* \param unsaved_files the Files that have not yet been saved to disk
* but may be required for parsing or code completion, including the
* contents of those files. The contents and name of these files (as
* specified by CXUnsavedFile) are copied when necessary, so the
* client only needs to guarantee their validity until the call to
* this function returns.
*
* \param num_unsaved_files The number of unsaved file entries in \p
* unsaved_files.
*
* \param options Extra options that control the behavior of code
* completion, expressed as a bitwise OR of the enumerators of the
* CXCodeComplete_Flags enumeration. The
* \c clang_defaultCodeCompleteOptions() function returns a default set
* of code-completion options.
