aaruf_lzma_decode_buffer()

int32_t aaruf_lzma_decode_buffer	(	uint8_t *	dst_buffer,
		size_t *	dst_size,
		const uint8_t *	src_buffer,
		size_t *	src_len,
		const uint8_t *	props,
		const size_t	props_size )

Decodes an LZMA-compressed buffer.

Decompresses data from the source buffer into the destination buffer using LZMA.

Parameters

dst_buffer	Pointer to the destination buffer.
dst_size	Pointer to the size of the destination buffer; updated with the actual size.
src_buffer	Pointer to the source (compressed) buffer.
src_len	Pointer to the size of the source buffer; updated with the actual size read.
props	Pointer to the LZMA properties.
props_size	Size of the LZMA properties.

Returns

0 on success, or an error code on failure.
