Function zstd_sys::ZSTD_DCtx_refDDict

pub unsafe extern "C" fn ZSTD_DCtx_refDDict(
    dctx: *mut ZSTD_DCtx, 
    ddict: *const ZSTD_DDict
) -> usize

ZSTD_DCtx_refDDict() : Reference a prepared dictionary, to be used to decompress next frames. The dictionary remains active for decompression of future frames using same DCtx. @result : 0, or an error code (which can be tested with ZSTD_isError()). Note 1 : Currently, only one dictionary can be managed. Referencing a new dictionary effectively "discards" any previous one. Special: referencing a NULL DDict means "return to no-dictionary mode". Note 2 : DDict is just referenced, its lifetime must outlive its usage from DCtx.
