WSAIoctl(SIO_GET_INTERFACE_LIST) works with Winsock 2.  Depending on the
OS, you get more or less the same info as SIOCGIFCONF.  So much similar,
in fact, that one of my tasks for the FAQ is to write a translator
between the two interfaces for the BSD compatibility item.

That gets you mainly IP addresses, masks, flags and other things.  If
instead you need adapter _names_, you can use GetInterfaceInfo(), part
of the IP Helper API on Windows 98 and Windows 2000.  Or, there's the
harder-to-use GetIfEntry(), which works on those two platforms, and on
WinNT 4 SP4+ as well.

Who says Windows is "unified"?
