函数名称：ZSTD_execSequenceLast7

函数原型：size_t ZSTD_execSequenceLast7(BYTE *op, BYTE *const oend, seq_t sequence, const BYTE **litPtr, const BYTE *const litLimit, const BYTE *const base, const BYTE *const vBase, const BYTE *const dictEnd)

返回类型：size_t

参数：

类型参数名称
BYTE *op
BYTE *constoend
seq_tsequence
const BYTE **litPtr
const BYTE *constlitLimit
const BYTE *constbase
const BYTE *constvBase
const BYTE *constdictEnd
883  oLitEnd等于op加litLength
884  sequenceLength等于litLength加matchLength
885  oMatchEnd等于op加sequenceLength
886  oend_w等于oend减! ZSTD_wildcopy() :* custom version of memcpy(), can copy up to 7 bytes too many (8 bytes if length==0)
887  iLitEnd等于litPtr加litLength
888  match等于oLitEnd减offset
891  如果oMatchEnd大于oend则返回:-***************************************** Error codes handling(dstSize_tooSmall)
893  如果iLitEnd大于litLimit则返回:-***************************************** Error codes handling(corruption_detected)
895  如果oLitEnd小于等于oend_w则返回:-***************************************** Error codes handling(GENERIC)
899  如果op小于oend_w则
900  ZSTD_wildcopy(op, * litPtr, oend_w - op)
901  litPtr加等于oend_w减op
902  op等于oend_w
904  当op小于oLitEnd循环
905  op自加等于*litPtr自加
908  如果offset大于oLitEnd减base则
910  如果offset大于oLitEnd减vBase则返回:-***************************************** Error codes handling(corruption_detected)
912  match等于dictEnd减base减match
913  如果match加matchLength小于等于dictEnd则
914  Not static to avoid a conflict with the prototype in the Linux headers.
915  返回:sequenceLength
919  length1等于dictEnd减match
920  Not static to avoid a conflict with the prototype in the Linux headers.
921  op等于oLitEnd加length1
922  matchLength减等于length1
923  match等于base
926  当op小于oMatchEnd循环
927  op自加等于match自加
928  返回:sequenceLength
