Can writes to a datagram socket ever raise SIGPIPE?

I'm working with some code that needs to be safe against killing the caller due to SIGPIPE, but the only socket writes it's performing are going to datagram sockets (both UDP and Unix domain datagram sockets). Do I need to worry about SIGPIPE? I'm using connect on the socket, but preliminary testing (on Linux) showed that I just get ECONNREFUSED on send if there's nobody listening on the Unix domain socket. Not sure what happens with UDP.

I can wrap the whole thing in hacks to get rid of SIGPIPE, but if it's a non-issue I'd rather save the overhead and keep the code complexity down.
