#define LZMA_CHECK_BEST   LZMA_CHECK_CRC32

Function Documentation

lzma_check_finish()

void lzma_check_finish ( lzma_check_state * check, lzma_check type )

extern

Finish the check calculation and store the result to check->buffer.u8.

lzma_check_init()

void lzma_check_init ( lzma_check_state * check, lzma_check type )

extern

Initialize *check depending on type.

Returns

LZMA_OK on success. LZMA_UNSUPPORTED_CHECK if the type is not supported by the current version or build of liblzma. LZMA_PROG_ERROR if type > LZMA_CHECK_ID_MAX.

lzma_check_update()

void lzma_check_update ( lzma_check_state * check, lzma_check type, const uint8_t * buf, size_t size )

extern

Update the check state.

lzma_sha256_finish()

void lzma_sha256_finish ( lzma_check_state * check )

extern

Finish the SHA-256 calculation and store the result to check->buffer.u8.

lzma_sha256_init()

void lzma_sha256_init ( lzma_check_state * check )

extern

Prepare SHA-256 state for new input.

lzma_sha256_update()

void lzma_sha256_update ( const uint8_t * buf, size_t size, lzma_check_state * check )

extern

Update the SHA-256 hash state.

Variable Documentation

lzma_crc32_table

const uint32_t lzma_crc32_table[8][256]

extern

lzma_crc32_table[0] is needed by LZ encoder so we need to keep the array two-dimensional.

lzma_crc64_table

const uint64_t lzma_crc64_table[4][256]

extern
