crc32 check

java标准库中有啊！！CRC32 crc32 = new CRC32();byte[] data = new byte[128];for(byte i=0;i<data.length;i++) { data[i] = i;} crc32.update(data);System.out.println(crc32.getValue());...

m_crc = crc32(m_crc, start, (uInt)(m_zstream.next_out - start)); start = m_zstream.next_out; if (getLong() != m_crc) { m_z_err = Z_DATA_ERROR; }else { (void)getLong(); check_header(); if (...
