Yikes! It turns out if_nameindex() doesn't return info for down devices, but if_indextoname() does. It's all so touchy... So, attached is an alternate patch using if_indextoname() that does work; my last one doesn't. Just for kicks I also attached a cpp file adapted from MSDN that can do a quick test. To build it do: $ wineg++ -c show-eths.cpp $ wineg++ -o show-eths.exe.so show-eths.o $ wine ./show-eths.exe.so You should get a listing for eth0 whether you boot with an ethernet connection or not. Note that to witness the problem you have to actually reboot with no ethernet connection. Just doing "ifdown eth0" isn't enough. > Cool, thanks for that.
