inet:getiflist() behaviour in Windows

In my Windows XP, the netstat -r shows that "0x1" as loopback
interface and "0x2" as ethernet.

However, if I do inet:ifget("0x1", [addr, flags]), returns {error, einval}.

Maybe the way of unix implementation and the windows are different.

I have a feeling that I should not use the undocumented function even
if it is exported publically.
