Distinguish between TCP and connected UDP sockets

I have a few functions written for TCP sockets and wish to use them for
connected UDP sockets. Most of the code is common, but I need a way to
distinguish between the two socket types given a descriptor. What's
the easiest way to do this?

Thanks in advance.

getsockopt(sock, SOL_SOCKET, SO_TYPE, ...)
