Function ZSTD_CCtx_setParameter

pub unsafe extern "C" fn ZSTD_CCtx_setParameter(
    cctx: *mut ZSTD_CCtx,
    param: ZSTD_cParameter,
    value: c_int,
) -> usize

ZSTD_CCtx_setParameter() : Set one compression parameter, selected by enum ZSTD_cParameter. All parameters have valid bounds. Bounds can be queried using ZSTD_cParam_getBounds(). Providing a value beyond bound will either clamp it, or trigger an error (depending on parameter). Setting a parameter is generally only possible during frame initialization (before starting compression). Exception : when using multi-threading mode (nbWorkers >= 1), the following parameters can be updated during compression (within same frame): => compressionLevel, hashLog, chainLog, searchLog, minMatch, targetLength and strategy. new parameters will be active for next job only (after a flush()). @return : an error code (which can be tested using ZSTD_isError()).
