But here's a question: if the peek offset is equal to the length, should the reading return an empty datagram? This would indicate to the caller that there was a datagram there, which was skipped over. That's how we deal with empty datagrams anyway. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
