GnomeAutoarformat_get_format_libarchive

Gets the format code used by libarchive. You can use the return value as the argument for archive_read_support_format_by_code() and archive_write_set_format(). However, some format cannot be set using these two functions because of problems inside libarchive. Use autoar_format_get_libarchive_read() and autoar_format_get_libarchive_write() to get the function pointer is the more reliable way to set format on the archive object.
