// CRC32 function
// To create a CRC from a new buffer, use this:
// crc = MakeCRC32(mydata, data_len, 0);
// If you need to continue the CRC (e.g. your data is in multiple buffers),
// continue like this:
// crc = MakeCRC32(moredata, more_len, crc);
//
// Your desired CRC should be the complement of the CRC generated by
// MakeCRC32:
// desired = crc
// desired - crc = 0
unsigned long MakeCRC32(char *data, unsigned int len, unsigned long CRC);
