Name:xz_crc32

Proto:uint32_t xz_crc32(const uint8_t *buf, size_t size, uint32_t crc)

Type:uint32_t

Parameter:

Type	Parameter	Name
const uint8_t *	buf
size_t	size

51

crc = ~crc

53

When size != 0 cycle

54

crc = xz_crc32_table[ * buf++ ^ (crc & 0xFF)] ^ crc >> 8

55

--size

58

Return ~crc

dec_block	Decode the Compressed Data field from a Block
index_update	Update the Index size and the CRC32 value.
dec_index	Decode the Number of Records, Unpadded Size, and Uncompressed Size* fields from the Index field. That is, Index Padding and CRC32 are not* decoded by this function.* This can return XZ_OK (more input needed), XZ_STREAM_END (everything
dec_stream_header	Decode the Stream Header field (the first 12 bytes of the .xz Stream).
