ZSTD_c_windowLog constant

int const ZSTD_c_windowLog

Maximum allowed back-reference distance, expressed as power of 2. This will set a memory budget for streaming decompression, with larger values requiring more memory and typically compressing more. Must be clamped between ZSTD_WINDOWLOG_MIN and ZSTD_WINDOWLOG_MAX. Special: value 0 means "use default windowLog". Note: Using a windowLog greater than ZSTD_WINDOWLOG_LIMIT_DEFAULT requires explicitly allowing such size at streaming decompression stage.

Implementation

static const int ZSTD_c_windowLog = 101;
