I would like to get the IP address of one of the interfaces of the
machine that I'm currently on from within some C++ code. It looks like
I should be able to do this by doing an

ioctl(atoi(fd, SIOCGIFADDR, &ifr)

with the interface name set in the appropriate field in ifr, but I'm not
sure how I should be getting the proper value for fd. I would
appreciate some help on this, or if there is a better way then I'd love
to hear it.

Thanks,

Chris
