+ * providing only the basic functionality needed to support development tools.
+ *
+ * To avoid namespace pollution, data types are prefixed with "CX" and

+ * method, rather than all of the overridden methods. For example, if

+ * Perform code completion at a given location in a translation unit.
+ *
+ * This function performs code completion at a particular file, line, and
+ * column within source code, providing results that suggest potential
+ * code snippets based on the context of the completion. The basic model
+ * for code completion is that Clang will parse a complete source file,
+ * performing syntax checking up to the location where code-completion has
+ * been requested. At that point, a special code-completion token is passed
+ * to the parser, which recognizes this token and determines, based on the
+ * current location in the C/Objective-C/C++ grammar and the state of
+ * 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
+ * user types punctuation characters or whitespace, at which point 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 ">",
+ * 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

+ * 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
