Field Documentation

block_size

uint64_t(* block_size)(const void *options)

Calculates the recommended Uncompressed Size for .xz Blocks to which the input data can be split to make multithreaded encoding possible. If this is NULL, it is assumed that the encoder is fast enough with single thread.

Calculates the recommended Uncompressed Size for .xz Blocks to which the input data can be split to make multithreaded encoding possible. If this is NULL, it is assumed that the encoder is fast enough with single thread. If the options are invalid, UINT64_MAX is returned.

id

lzma_vli id

Filter ID.

init

lzma_init_function init

Initializes the filter encoder and calls lzma_next_filter_init() for filters + 1.

memusage

uint64_t(* memusage)(const void *options)

Calculates memory usage of the encoder. If the options are invalid, UINT64_MAX is returned.

props_encode

lzma_ret(* props_encode)(const void *options, uint8_t *out)

Encodes Filter Properties.

Returns

- LZMA_OK: Properties encoded successfully.

• LZMA_OPTIONS_ERROR: Unsupported options
• LZMA_PROG_ERROR: Invalid options or not enough output space

props_size_fixed

uint32_t props_size_fixed

Some filters will always have the same size Filter Properties field. If props_size_get is NULL, this value is used.

props_size_get

lzma_ret(* props_size_get)(uint32_t *size, const void *options)

Tells the size of the Filter Properties field. If options are invalid, UINT32_MAX is returned. If this is NULL, props_size_fixed is used.

Tells the size of the Filter Properties field. If options are invalid, LZMA_OPTIONS_ERROR is returned and size is set to UINT32_MAX.
