返回类型：size_t

参数：

类型参数名称
ZSTD_CCtx *zc
void *dst
size_tdstCapacity
const void *src
size_tsrcSize
2335  blockCompressor等于ZSTD_selectBlockCompressor(strategy, lowLimit < dictLimit)
2336  base等于base
2337  istart等于src
2338  curr等于istart减base
2339  如果srcSize小于r a non-null block 加ZSTD_blockHeaderSize加1则返回:0
2341  -************************************** Sequence storage
2342  如果curr大于nextToUpdate加384则nextToUpdate等于curr减-************************************** shared macros(192, (U32)(curr - nextToUpdate - 384))
2344  blockCompressor(zc, src, srcSize)
2345  返回:ZSTD_compressSequences(zc, dst, dstCapacity, srcSize)
