buf

uint8_t lzma_lzma2_coder::buf[LZMA2_HEADER_MAX+LZMA2_CHUNK_MAX]

Buffer to hold the chunk header and LZMA compressed data.

Definition at line 50 of file lzma2_encoder.c.

Referenced by lzma2_header_lzma(), and lzma2_header_uncompressed().

buf_pos

size_t lzma_lzma2_coder::buf_pos

Read position in buf[].

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.
