Macro Definition Documentation

LZMA_FILTER_DELTA

#define LZMA_FILTER_DELTA   LZMA_VLI_C(0x03)

Filter ID.

Filter ID of the Delta filter. This is used as lzma_filter.id.

Enumeration Type Documentation

lzma_delta_type

enum lzma_delta_type

Type of the delta calculation.

Currently only byte-wise delta is supported. Other possible types could be, for example, delta of 16/32/64-bit little/big endian integers, but these are not currently planned since byte-wise delta is almost as good.
