You have to issue the ioctl call on a so-called `dummy' socket.
Just open a simple socket, e.g.
fd = socket(AF_INET, SOCK_DGRAM, 0);
(check for error)
ioctl(fd, SIOCGIFADDR, &ifr); (ifr.ifr_name holds the iface name)
(I don't know what you'd like to do with that atoi :))

A better way should be using (open/create) a netlink socket.
Unfortunatly I don't know how to do this ;) (I have to read and learn
netlink `programming').
That said I'm not 100% sure about this (netlink stuff) :)
By the way, if someone could post some `netlink' examples, links, and so
on :) thanks.
