From b34081f1cd59585451efaa69e1dff1b9507e6c89 Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Wed, 11 Sep 2013 14:26:32 -0700 Subject: lz4: fix compression/decompression signedness mismatch LZ4 compression and decompression functions require different in signedness input/output parameters: unsigned char for compression and signed char for decompression. Change decompression API to require "(const) unsigned char *".
