I am working on a Gnome Applet which monitor & configure our SiS 900
chip/card.
Basically, you need a (rather dummy) socket and ifreq structure. Open the
socket
with AF_INET and SOCK_DGRAM. Assign the interface you want to
configure in ifreq.ifr_name the call ioctl with various SIOC**** to get/set
value you want about an interface.
For more information, take a look at /usr/include/net/if.h and
/usr/include/bits/ioctls.h
