函数名称： : 0 if success, or an error code, which can be tested using ZSTD_isError()

函数原型：static size_t ZSTD_decodeFrameHeader(ZSTD_DCtx *dctx, const void *src, size_t headerSize)

返回类型：size_t

参数：

类型参数名称
ZSTD_DCtx *dctx
const void *src
size_theaderSize

摘要：ZSTD_decodeFrameHeader() :* `headerSize` must be the size provided by ZSTD_frameHeaderSize().

374  result等于 : 0, `fparamsPtr` is correctly filled,
375  如果ZSTD_isError() - tells if a size_t function result is an error code*@code: The function result to check for error.* Return: Non-zero iff the code is an error.则返回:result
377  如果result大于0则返回:-***************************************** Error codes handling(srcSize_wrong)
379  如果dictID且dictID不等于dictID则返回:-***************************************** Error codes handling(dictionary_wrong)
381  如果checksumFlag则xxh64_reset( & xxhState, 0)
383  返回:0
