函数名称:ZSTD_decompressSequences

函数原型:static size_t ZSTD_decompressSequences(ZSTD_DCtx *dctx, void *dst, size_t maxDstSize, const void *seqStart, size_t seqSize)

返回类型:size_t

参数:

类型参数名称
ZSTD_DCtx *dctx
void *dst
size_tmaxDstSize
const void *seqStart
size_tseqSize
1095  ip等于seqStart
1096  iend等于ipseqSize
1097  ostart等于dst
1098  oend等于ostartmaxDstSize
1099  op等于ostart
1100  litPtr等于litPtr
1101  litEnd等于litPtrlitSize
1102  base等于base
1103  vBase等于vBase
1104  dictEnd等于dictEnd
1109  seqHSize等于ZSTD_decodeSeqHeaders(dctx, & nbSeq, ip, seqSize)
1110  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:seqHSize
1112  ip加等于seqHSize
1116  如果nbSeq
1118  fseEntropy等于1
1121 i小于umber of repcodes 循环prevOffset[i]等于rep[i]
1146 i小于umber of repcodes 循环rep[i]等于prevOffset[i]
1153  lastLLSize等于litEndlitPtr
1154  如果lastLLSize大于oendop则返回:-***************************************** Error codes handling(dstSize_tooSmall)
1156  内存复制(op, litPtr, lastLLSize)
1157  op加等于lastLLSize
1160  返回:opostart
