函数原型：size_t ZSTD_endStream(ZSTD_CStream *zcs, ZSTD_outBuffer *output)

返回类型：size_t

参数：

类型参数名称
ZSTD_CStream *zcs
ZSTD_outBuffer *output
3253  ostart等于dst加pos
3254  oend等于dst加size
3255  op等于ostart
3257  如果pledgedSrcSize且inputProcessed不等于pledgedSrcSize则返回:-***************************************** Error codes handling(srcSize_wrong)
3260  如果stage不等于zcss_final则
3262  srcSize等于0
3263  sizeWritten等于size减pos
3264  notEnded等于ZSTD_compressStream_generic(zcs, ostart, & sizeWritten, & srcSize, & srcSize, zsf_end)
3266  remainingToFlush等于outBuffContentSize减outBuffFlushedSize
3267  op加等于sizeWritten
3268  如果remainingToFlush则
3269  pos加等于sizeWritten
3270  返回:remainingToFlush加C standard doesn't allow `static const` variable to be init using another `static const` variable 加checksum乘4
3273  stage等于zcss_final
3274  outBuffContentSize等于如果非notEnded则0否则ZSTD_compressEnd(cctx, outBuff, outBuffSize, NULL, 0)
3280  toFlush等于outBuffContentSize减outBuffFlushedSize
3281  flushed等于ZSTD_limitCopy(op, oend - op, outBuff + outBuffFlushedSize, toFlush)
3282  op加等于flushed
3283  outBuffFlushedSize加等于flushed
3284  pos加等于op减ostart
3285  如果toFlush恒等于flushed则stage等于zcss_init
3287  返回:toFlush减flushed
