It's been a while since I've done socket programming, but if I remember
correctly, what you want to do is use "gethostname" to get youre host's
real name, and then "gethostbyname" to look up the IP. Note that if you
have more than one interface, it becomes more complicated. Probably irrelevant
in the WinDoze world, though.
