Function Documentation

static void copy_and_encode	(	lzma_coder *	coder,
		const uint8_t *restrict	in,
		uint8_t *restrict	out,
		size_t	size
	)			[static]

Copies and encodes the data at the same time. This is used when Delta is the first filter in the chain (and thus the last filter in the encoder's filter stack).

References lzma_coder_s::distance, lzma_coder_s::history, and lzma_coder_s::pos.

static void encode_in_place	(	lzma_coder *	coder,
		uint8_t *	buffer,
		size_t	size
	)			[static]

Encodes the data in place. This is used when we are the last filter in the chain (and thus non-last filter in the encoder's filter stack).
