I am trying to put a small interface info tool

The aim is to produce something like

flags: up running multicast
address: <fe80::9953:b1f5:a643:4497%15>

Local Area Connection
I am using getifaddrs to obtain all the AF_INET and AF_INET6
interface, however I can only obtain the friendly name of the
AF_INET using
ioctl(sock, SIOCGIFFRNDLYNAM
On my pc I see 20 interface, 10 for each type, however
only 7 couples shares the same "ifa_name" the others
3+3 shows different ones.
Btw., don't use the friendly names to distinguish interfaces. Only the
real, GUID-like interface name is a valid, unique identifier under
Windows.

That I know, however If I should advise a user to disable by control
panel a virtual interface I can not use the
{9F4F7FD2-5E44-4796-ABE0-0785CF76C11E}
but
"Local Area Connection"
should work ...
