        The zzip_file_real function checks if the ZZIP_FILE-handle is wrapping a real file or a zip-contained
       file. Returns 1 for a stat'able file, and 0 for a file inside a zip-archive.

        The zzip_dir_real function checks if the ZZIP_DIR-handle is wrapping a real directory or a zip-archive.
       Returns 1 for a stat'able directory, and 0 for a handle to zip-archive.

        The zzip_realdir function returns the posix DIR* handle (if one exists). Check before with zzip_dir_real
       if the the ZZIP_DIR points to a real directory.

        The zzip_realfd function returns the posix file descriptor (if one exists). Check before with
       zzip_file_real if the the ZZIP_FILE points to a real file.
