Function zstd_sys::ZSTD_CCtx_refCDict

pub unsafe extern "C" fn ZSTD_CCtx_refCDict(
    cctx: *mut ZSTD_CCtx, 
    cdict: *const ZSTD_CDict
) -> usize

ZSTD_CCtx_refCDict() : Reference a prepared dictionary, to be used for all next compression jobs. Note that compression parameters are enforced from within CDict, and supercede any compression parameter previously set within CCtx. The dictionary will remain valid for future compression jobs using same CCtx. @result : 0, or an error code (which can be tested with ZSTD_isError()). Special : adding a NULL CDict means "return to no-dictionary mode". Note 1 : Currently, only one dictionary can be managed. Adding a new dictionary effectively "discards" any previous one. Note 2 : CDict is just referenced, its lifetime must outlive CCtx.
