The "default" has been IPv4 and would seem to be the "right" thing to return once we find an address; however, if we wanted an IPv6 address and returned an IPv4 one, that wouldn't be good...
Thanks your review and help and i have changed some place for this part, please see the email i replied before(just now).
Leaving the following - including the capability to get either IPv6 or IPv4 address depending upon what's desired/required: for (ifa = ifap; ifa; ifa = ifa->ifa_next) { if (!ifa->ifa_addr || STRNEQ(ifa->ifa_name, ifname)) continue; found_one = true; if (want_ipv6 && ifa->ifa_addr->sa_family != AF_INET6) continue; /* Found an address to return */ addr->data.stor.ss_family = ifa->ifa_addr->sa_family; if (ifa->ifa_addr->sa_family == AF_INET6) addr->len = sizeof(addr->data.inet6); memcpy(&addr->data.inet6, ifa->ifa_addr, addr->len); } else {} else if (!want_ipv6 && ifa->ifa_addr->sa_family == AF_INET) {addr->len = sizeof(addr->data.inet4); memcpy(&addr->data.inet4, ifa->ifa_addr, addr->len); } ret = 0; goto cleanup; }
