This is probably the easiest approach. Another is to try to get the TCP option TCP_MAXSEG and if it fails, it is a UDP socket.

You can, however, get the info you want if you are using Linux. I don't know about other OSs as I don't have any other development platforms here. If you do a 

getsockopt SOCK, SOL_SOCKET, SO_TYPE;

[download]
it will (should?) return SOCK_STREAM for stream (TCP) sockets and SOCK_DGRAM for datagram (UDP) sockets. This looks like it works from C, but on my perl5.005003 it seems to have a problem. Maybe it's my system...
