See the tun(4) manpage, it describes the tun interface. It refers to
'the usual network-interface ioctl(2)s, such as SIOCSIFADDR and SIOCSIFNETMAS'.
I think in this case you need something like SIOCGIFADDR. As usual
when talking about network interfaces, my recommendation would be
'see the ifconfig(8) source, ifconfig usually knows how to do its job'.
Hope that helps.
G'luck,
Peter
