参数：

类型参数名称
deflate_state *s
1076  n等于0
1077  ascii_freq等于0
1078  bin_freq等于0
1079  当n小于7循环
1079  bin_freq加等于Freq
1080  当n小于128循环
1080  ascii_freq加等于Freq
1081  当n小于umber of length codes, not counting the special END_BLOCK code 循环
1081  bin_freq加等于Freq
1082  UNKNOWN, BINARY or ASCII 等于如果bin_freq大于ascii_freq右移2位则compression strategy; see deflateInit2() below for details 否则Z_ASCII

名称描述
zlib_tr_flush_blockDetermine the best encoding for the current block: dynamic trees, static* trees or store, and output the encoded block to the zip file. This function* returns the total compressed length for the file so far.
