函数名称：compress_block

函数原型：static void compress_block(deflate_state *s, ct_data *ltree, ct_data *dtree)

返回类型：void

参数：

类型参数名称
deflate_state *s
ct_data *ltree
ct_data *dtree
1026  lx等于0
1030  如果unning index in l_buf 不等于0则循环
1031  dist等于d_buf[lx]
1032  lc等于uffer for literals or lengths [lx++]
1033  如果dist恒等于0则
1034  send_code(s, lc, ltree)
1036  否则
1038  code等于distance codes. The first 256 values correspond to the distances* 3 .. 258, the last 256 values correspond to the top 8 bits of* the 15 bit distances.[lc]
1039  send_code(s, code + umber of length codes, not counting the special END_BLOCK code + 1, ltree)
1040  extra等于peat a zero length 11-138 times (7 bits of repeat count) [code]
1041  如果extra不等于0则
1045  dist自减
1046  code等于d_code(dist)
1049  send_code(s, code, dtree)
1050  extra等于extra_dbits[code]
1051  如果extra不等于0则
1060  当lx小于unning index in l_buf 循环
1062  send_code(s, Bit length codes must not exceed MAX_BL_BITS bits , ltree)
1063  length of EOB code for last block 等于Len

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.
