函数名称：lm_init

函数原型：static void lm_init(deflate_state *s)

返回类型：void

参数：

类型参数名称
deflate_state *s
523  Sliding window等于2L乘LZ77 window size (32K by default)
529  To speed up deflation, hash chains are never searched beyond this* length. A higher limit improves compression ratio but degrades the* speed.等于do not perform lazy search above this match length
530  good_match等于duce lazy search above this match length
531  Stop searching when current match exceeds this 等于quit search above this match length
532  Length of the best match at previous step. Matches not greater than this* are discarded. This is used in the lazy match evaluation.等于max_chain
534  start of string to insert 等于0
535  Number of bits by which ins_h must be shifted at each input* step. It must be such that after MIN_MATCH steps, the oldest* byte no longer takes part in the hash key, that is:* hash_shift * MIN_MATCH >= hash_bits等于0L
536  umber of valid bytes ahead in window 等于0
537  length of best match 等于prev_length等于The three kinds of block type 减1
538  set if previous match exists 等于0
539  hash index of string to be inserted 等于0
