424  如果非FIXME: Not all basic memory functions are provided in architecture-specific* files (yet). We define our own versions here for now, but this should be* only a temporary solution.* memeq and memzero are not used much and any remotely sane implementation则返回:XZ_DATA_ERROR
427  如果xz_crc32(buf + 4, 6, 0)不等于get_le32(buf)则返回:XZ_DATA_ERROR
435  如果Size of the Index in bytes 右移2位不等于get_le32(buf + 4)则返回:XZ_DATA_ERROR
438  如果buf[8]不等于0或buf[9]不等于 Type of the integrity check calculated from uncompressed data 则返回:XZ_DATA_ERROR
