OT: getting the protocol family of a file descriptor

[Heiko Wundram (Beenic)]

Hey all!

I'm currently in the need to get the protocol family that was used to create a 
socket (and passed via a unix domain socket to another program), and I've not 
really come up with a proper scheme other than to use getsockname and 
retrieve sa_family from the resulting socket (which currently matches the 
socket domain and historically has, but why take the chances ;-)).

Is there any other "better" way to get at the domain (protocol family) of a 
socket?
