Procedures

BlockDecodeRaw

Decode LZ4 block format data from src to dst. Operates directly on raw memory data. Source size is limited to 16777215 bytes in order to simplify the code. Return decoded length if success or error code on failure.

PROCEDURE BlockDecodeRaw*(dst : ADDRESS; dlen : LENGTH; src : ADDRESS; slen : LENGTH): INTEGER;

MaxEncodeSize

Worst case needed destination for encoded data

PROCEDURE MaxEncodeSize*(slen : LENGTH): LENGTH;

BlockEncodeRaw

Encode raw memory data in src to LZ4 block format data in dst. Return encoded length if success or error code on failure.

PROCEDURE BlockEncodeRaw*(dst : ADDRESS; dlen : LENGTH; src : ADDRESS; slen : LENGTH): INTEGER;
