lm_init

Name:lm_init

Proto:static void lm_init(deflate_state *s)

Type:void

Parameter:

Type	Parameter	Name
deflate_state *	s

523

Sliding window = 2L * 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. = do not perform lazy search above this match length

530

good_match = duce lazy search above this match length

531

Stop searching when current match exceeds this = 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. = max_chain

534

start of string to insert = 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 = 0L

536

umber of valid bytes ahead in window = 0

537

length of best match = prev_length = The three kinds of block type - 1

538

set if previous match exists = 0

539

hash index of string to be inserted = 0
