getifaddrs() is indeed the right beast, though who knows, maybe you'll
have to filter out 127.0.0.1.  Hitch is, Linux doesn't provide it.
Here's an implementation I've used with good results that tries to
be portable (I've only tested it on linux, but it claims to handle Solaris):

Wish I had time to code a patch for you, too, but at least this might help.
