When using asio with an async udp connection can I assume I will always receive a complete datagram or nothing at all? If packets are lost I will get nothing. If I get a data read callback I can assume the entire datagram has been received and assembled (even if it consisted of multiple packets)? Some of the underlying assumptions aren't clear from the documentation. Thanks! -- Cause united breaks guitars http://www.youtube.com/watch?v=5YGc4zOqozo
