Function zstd_sys::ZSTD_initCStream_srcSize

pub unsafe extern "C" fn ZSTD_initCStream_srcSize(

Expand description

ZSTD_initCStream_srcSize() : This function is DEPRECATED, and equivalent to: ZSTD_CCtx_reset(zcs, ZSTD_reset_session_only); ZSTD_CCtx_refCDict(zcs, NULL); // clear the dictionary (if any) ZSTD_CCtx_setParameter(zcs, ZSTD_c_compressionLevel, compressionLevel); ZSTD_CCtx_setPledgedSrcSize(zcs, pledgedSrcSize);

pledgedSrcSize must be correct. If it is not known at init time, use ZSTD_CONTENTSIZE_UNKNOWN. Note that, for compatibility with older programs, “0” also disables frame content size field. It may be enabled in the future. This prototype will generate compilation warnings.
