函数名称：dictionary saving

函数原型：int LZ4_saveDictHC(LZ4_streamHC_t *LZ4_streamHCPtr, char *safeBuffer, int dictSize)

返回类型：int

参数：

类型参数名称
LZ4_streamHC_t *LZ4_streamHCPtr
char *safeBuffer
intdictSize
739  streamPtr等于internal_donotuse
740  prefixSize等于xt block to continue on current prefix 减All index relative to this position 加low that point, need extDict
743  如果dictSize大于64乘KB则dictSize等于64乘KB
745  如果dictSize小于4则dictSize等于0
747  如果dictSize大于prefixSize则dictSize等于prefixSize
750  Not static to avoid a conflict with the prototype in the Linux headers.
753  endIndex等于xt block to continue on current prefix 减All index relative to this position
755  xt block to continue on current prefix 等于safeBuffer加dictSize
756  All index relative to this position 等于xt block to continue on current prefix 减endIndex
757  low that point, need extDict 等于endIndex减dictSize
758  low that point, no more dict 等于endIndex减dictSize
760  如果dex from which to continue dict update 小于low that point, need extDict 则dex from which to continue dict update 等于low that point, need extDict
763  返回:dictSize
