Strruct ifall has a member ifa_frndlyname, type struct ifreq_frndlyname, which is filled for AF_INET and AF_INET6 interfaces. > 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. > > Any alternative to ioctl(sock, SIOCGIFFRNDLYNAM > for AF_INET6 ?
