Field Documentation

next_sequence

enum sequence lzma_lzma2_coder::next_sequence

Sequence after the size fields have been decoded.

lzma [1/2]

lzma_lz_decoder lzma_lzma2_coder::lzma

LZMA decoder.

uncompressed_size

size_t lzma_lzma2_coder::uncompressed_size

Uncompressed size of LZMA chunk.

Uncompressed size of a chunk.

compressed_size

size_t lzma_lzma2_coder::compressed_size

Compressed size of the chunk (naturally equals to uncompressed size of uncompressed chunk)

Compressed size of a chunk (excluding headers); this is also used to indicate the end of buf[] in SEQ_LZMA_COPY.

need_properties

bool lzma_lzma2_coder::need_properties

True if properties are needed. This is false before the first LZMA chunk.

need_dictionary_reset

bool lzma_lzma2_coder::need_dictionary_reset

True if dictionary reset is needed. This is false before the first chunk (LZMA or uncompressed).

lzma [2/2]

void* lzma_lzma2_coder::lzma

LZMA encoder.

opt_cur

lzma_options_lzma lzma_lzma2_coder::opt_cur

LZMA options currently in use.

buf_pos

size_t lzma_lzma2_coder::buf_pos

Read position in buf[].

buf

uint8_t lzma_lzma2_coder::buf[LZMA2_HEADER_MAX+LZMA2_CHUNK_MAX]

Buffer to hold the chunk header and LZMA compressed data.
