ZSTD_c_compressionLevel constant
int
const ZSTD_c_compressionLevel
Set compression parameters according to pre-defined cLevel table. Note that exact compression parameters are dynamically determined, depending on both compression level and srcSize (when known). Default level is ZSTD_CLEVEL_DEFAULT==3. Special: value 0 means default, which is controlled by ZSTD_CLEVEL_DEFAULT. Note 1 : it's possible to pass a negative compression level. Note 2 : setting a level does not automatically set all other compression parameters to default. Setting this will however eventually dynamically impact the compression parameters which have not been manually set. The manually set ones will 'stick'.
Implementation
static const int ZSTD_c_compressionLevel = 100;
