Flags
-----
SANITIZE_ALLOW_COLONS: Allow colons.
Without this flag colons are sanitized.
SANITIZE_ALLOW_PATH: Allow path separators and colons.
Without this flag path separators and colons are sanitized.
SANITIZE_ALLOW_RESERVED: Allow reserved device names.
Without this flag a reserved device name is renamed (COM1 => _COM1) unless it's
in a UNC prefixed path.
SANITIZE_ALLOW_TRUNCATE: Allow truncating a long filename.
Without this flag if the sanitized filename or path will be too long an error
occurs. With this flag the filename --and not any other parts of the path-- may
be truncated to at least a single character. A filename followed by an
alternate data stream (ADS) cannot be truncated in any case.
Success: (SANITIZE_ERR_OK) *sanitized points to a sanitized copy of file_name.
Failure: (!= SANITIZE_ERR_OK) *sanitized is NULL.
