\brief Reparse the source files that produced this translation unit.
This routine can be used to re-parse the source files that originally
created the given translation unit, for example because those source files
have changed (either on disk or as passed via \p unsaved_files). The
source code will be reparsed with the same command-line options as it
was originally parsed.
Reparsing a translation unit invalidates all cursors and source locations
that refer into that translation unit. This makes reparsing a translation
unit semantically equivalent to destroying the translation unit and then
creating a new translation unit with the same command-line arguments.
However, it may be more efficient to reparse a translation
unit using this routine.
\param TU The translation unit whose contents will be re-parsed. The
translation unit must originally have been built with
\c clang_createTranslationUnitFromSourceFile().
\param num_unsaved_files The number of unsaved file entries in \p
unsaved_files.
\param unsaved_files The files that have not yet been saved to disk
but may be required for parsing, 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 options A bitset of options composed of the flags in CXReparse_Flags.
The function \c clang_defaultReparseOptions() produces a default set of
options recommended for most uses, based on the translation unit.
\returns 0 if the sources could be reparsed. A non-zero error code will be
returned if reparsing was impossible, such that the translation unit is
invalid. In such cases, the only valid call for \c TU is
\c clang_disposeTranslationUnit(TU). The error codes returned by this
routine are described by the \c CXErrorCode enum.
