返回类型：size_t

参数：

类型参数名称
ZSTD_DCtx *dctx
const void *dict
size_tdictSize
1945  如果dictSize小于8则返回:ZSTD_refDictContent(dctx, dict, dictSize)
1948  magic等于ZSTD_readLE32(dict)
1949  如果magic不等于v0.7+ 则
1950  返回:ZSTD_refDictContent(dctx, dict, dictSize)
1953  dictID等于ZSTD_readLE32((constchar * )dict + 4)
1957  eSize等于 : size of entropy tables read
1958  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:-***************************************** Error codes handling(dictionary_corrupted)
1960  dict等于dict加eSize
1961  dictSize减等于eSize
1963  litEntropy等于fseEntropy等于1
1966  返回:ZSTD_refDictContent(dctx, dict, dictSize)
