函数名称：ZSTD_decompressBlock_internal

函数原型：static size_t ZSTD_decompressBlock_internal(ZSTD_DCtx *dctx, void *dst, size_t dstCapacity, const void *src, size_t srcSize)

返回类型：size_t

参数：

类型参数名称
ZSTD_DCtx *dctx
void *dst
size_tdstCapacity
const void *src
size_tsrcSize
1447  ip等于src
1449  如果srcSize大于等于Define for static allocation 则返回:-***************************************** Error codes handling(srcSize_wrong)
1454  litCSize等于 : nb of bytes read from src (< srcSize )
1455  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:litCSize
1457  ip加等于litCSize
1458  srcSize减等于litCSize
1460  如果sizeof(size_t)大于4则如果windowSize大于1左移23位则
1465  返回:ZSTD_decompressSequencesLong(dctx, dst, dstCapacity, ip, srcSize)
1466  返回:ZSTD_decompressSequences(dctx, dst, dstCapacity, ip, srcSize)
