The error code should be ENODEV.

A separate problem is determining whether an interface is operational and
whether it supports bi-directional communication.  GetAdaptersInfo() call on
Win32 does not provide any indication of whether an adapter is actually up
and running, I found that GetAdaptersAddresses() does not currently work on
Wine - it always returns success when trying to find the buffer size.

The call GetUniDirectionalAdapterInfo() is rather unusual, the only
unidirectional interfaces I can find are satellite feeds:
