Do you open AF_INET or AF_INET6?
Granted, I haven't tested and I'm only working with IPv4 at the moment with uClibc. Then "sysctl()" is supposed to be the successor of "ioctl()". UNP talks about using the routing sockets to get the information for each interface (sounds similar to netlink, but different enough). >>> >>> >> What does ifconfig do in BusyBox?

At least then it was usable for a bunch of different targets. FreeBSD behaves even more different to SIOCGIFCONF in that it reports all kinds of connections (AF_LINK also as well as IPv6) with duplicates.
