+ * 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_".

+ *
+ * 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 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 complete_column The column at which code-completion should occur.

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