	I believe getifaddrs(3) is the way to go.  SIOCGIFCONF is too hard to
	use.  the code is available under BSD license, and can be found in
	*BSD lib/libc/net/getifaddrs.c.  we can ship it in "missing" directory 
	(i'm not sure if it works on random other OSes or not, but it looks
	to be portable and it does provide a good API wrapping to the issue).

	the function was originated in Stevens book, and implemented by BSDI.
