通过源数据长度来判别第二个参数是Z_NO_FLUSH还是Z_FINISH(这里我们知道deflate第二个参数可以输入两个中参数Z_NO_FLUSH或Z_FINISH),即如果源数据长度为0,第二个参数为Z_FINISH,否则为Z_NO_FLUSH。deflate返回值为Z_OK为正常状态,返回Z_STREAM_END,代表流结束(也就是全部压缩完毕),其他都为err状态。 do{ ....

a flush call is made to align the deflate data with a byte boundary. In one example, the flush call is a Z_SYNCH_FLUSH call. According to various embodiments, a deflated portion can then only be padded with a specific 2 byte sequence, a specific 5 byte sequence, and two specific 6 ...
