ZSTD_c_enableLongDistanceMatching constant

int const ZSTD_c_enableLongDistanceMatching

Enable long distance matching. This parameter is designed to improve compression ratio for large inputs, by finding large matches at long distance. It increases memory usage and window size. Note: enabling this parameter increases default ZSTD_c_windowLog to 128 MB except when expressly set to a different value. Note: will be enabled by default if ZSTD_c_windowLog >= 128 MB and compression strategy >= ZSTD_btopt (== compression level 16+)

Implementation

static const int ZSTD_c_enableLongDistanceMatching = 160;
