57/** \defgroup CINDEX libclang: C Interface to Clang
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_".

239 * header that was used by the translation unit. If zero, all declarations
240 * will be enumerated.

247 *

250 * TU = clang_createTranslationUnit(Idx, "IndexTest.pch");
251 *
252 * // This will load all the symbols from 'IndexTest.pch'
253 * clang_visitChildren(clang_getTranslationUnitCursor(TU),
254 * TranslationUnitVisitor, 0);
255 * clang_disposeTranslationUnit(TU);

263 * TranslationUnitVisitor, 0);

265 * \endcode

267 * This process of creating the 'pch', loading it separately, and using it (via

269 * (which gives the indexer the same performance benefit as the compiler).

2760 * In both Objective-C and C++, a method (aka virtual member function,

2762 * Objective-C, a method is said to override any method in the class's

2767 * implementation is considered to override the same methods as its
2768 * corresponding method in the interface.
2769 *
2770 * For C++, a virtual member function overrides any virtual member
2771 * function with the same signature that occurs in its base
2772 * classes. With multiple inheritance, a virtual member function can
2773 * override several virtual member functions coming from different
2774 * base classes.
2775 *
2776 * In all cases, this function determines the immediate overridden
2777 * method, rather than all of the overridden methods. For example, if

2779 * (which in inherits from A) and also in C (which inherited from B),
2780 * then the only overridden method returned from this function when

5222 * string for its representation, which is accessible via
5223 * \c clang_getCompletionChunkCompletionString(). The code-completion string
5224 * describes an additional part of the template that is completely optional.

5239 * - an Optional chunk containing the last defaulted argument:
5240 * - a Comma chunk for ","
5241 * - a Placeholder chunk for "double z"
5242 * - a RightParen chunk for ")"
5243 *
5244 * There are many ways to handle Optional chunks. Two simple approaches are:
5245 * - Completely ignore optional chunks, in which case the template for the
5246 * function "f" would only include the first parameter ("int x").
5247 * - Fully expand all optional chunks, in which case the template for the

5782/**
5783 * Perform code completion at a given location in a translation unit.
5784 *
5785 * This function performs code completion at a particular file, line, and
5786 * column within source code, providing results that suggest potential
5787 * code snippets based on the context of the completion. The basic model
5788 * for code completion is that Clang will parse a complete source file,
5789 * performing syntax checking up to the location where code-completion has
5790 * been requested. At that point, a special code-completion token is passed
5791 * to the parser, which recognizes this token and determines, based on the
5792 * current location in the C/Objective-C/C++ grammar and the state of
5793 * semantic analysis, what completions to provide. These completions are
5794 * returned via a new \c CXCodeCompleteResults structure.
5795 *
5796 * Code completion itself is meant to be triggered by the client when the
5797 * user types punctuation characters or whitespace, at which point the
5798 * code-completion location will coincide with the cursor. For example, if \c p
5799 * is a pointer, code-completion might be triggered after the "-" and then
5800 * after the ">" in \c p->. When the code-completion location is after the ">",
5801 * the completion results will provide, e.g., the members of the struct that
5802 * "p" points to. The client is responsible for placing the cursor at the
5803 * beginning of the token currently being typed, then filtering the results
5804 * based on the contents of the token. For example, when code-completing for
5805 * the expression \c p->get, the client should provide the location just after
5806 * the ">" (e.g., pointing at the "g") to this code-completion hook. Then, the
5807 * client can filter the results based on the current token text ("get"), only
5808 * showing those results that start with "get". The intent of this interface
5809 * is to separate the relatively high-latency acquisition of code-completion
5810 * results from the filtering of results on a per-character basis, which must
5811 * have a lower latency.
5812 *
5813 * \param TU The translation unit in which code-completion should
5814 * occur. The source files for this translation unit need not be
5815 * completely up-to-date (and the contents of those source files may
5816 * be overridden via \p unsaved_files). Cursors referring into the
5817 * translation unit may be invalidated by this invocation.
5818 *
5819 * \param complete_filename The name of the source file where code
5820 * completion should be performed. This filename may be any file
5821 * included in the translation unit.
5822 *
5823 * \param complete_line The line at which code-completion should occur.
5824 *
5825 * \param complete_column The column at which code-completion should occur.
5826 * Note that the column should point just after the syntactic construct that
5827 * initiated code completion, and not in the middle of a lexical token.
5828 *
5829 * \param unsaved_files the Files that have not yet been saved to disk
5830 * but may be required for parsing or code completion, including the
5831 * contents of those files. The contents and name of these files (as
5832 * specified by CXUnsavedFile) are copied when necessary, so the
5833 * client only needs to guarantee their validity until the call to
5834 * this function returns.
5835 *
5836 * \param num_unsaved_files The number of unsaved file entries in \p
5837 * unsaved_files.

5840 * completion, expressed as a bitwise OR of the enumerators of the
5841 * CXCodeComplete_Flags enumeration. The
5842 * \c clang_defaultCodeCompleteOptions() function returns a default set
5843 * of code-completion options.
5844 *
5845 * \returns If successful, a new \c CXCodeCompleteResults structure
