NETWORKING - Portable way to get list of all active network interfaces

I would like to get the list of all active network interfaces (e.g. eth0, wlan0). I assume I'll have to parse the output of ifconfig, but the formatting is different across the various OS's. Does anybody have a portable way to get this information so it can be used on the majority of unices (linux, *bsd, mac).
