Unfortunately, all I've been getting is empty addresses. This is the output from ifconfig -a: <snip> en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 134.14.55.116 netmask 0xffffff00 broadcast 134.14.55.255 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 192.168.0.116 netmask 0xffffff00 broadcast 192.168.0.255 fw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 4078 lladdr 00:0a:95:ff:fe:79:5c:fc media: autoselect <full-duplex> status: inactive supported media: autoselect <full-duplex> <snip> This is what I did to get the interface addresses: ifnet_t *list = NULL; ifaddr_t *addresses = NULL; uint32_t count = 0; struct sockaddr out_addr; int i = 0; int j = 0; int err = 0; struct in_addr pin; if (!ifnet_list_get(AF_INET, &list, &count)) { for (i = 0; i < count; i++) { if (!ifnet_get_address_list(list[i], &addresses)) { for (j = 0; addresses[j] != NULL; j++) { if ((err = ifaddr_address(addresses[j], &out_addr, sizeof(struct sockaddr))) == 0) { if (inet_aton(out_addr.sa_data, &pin)) PRINTF("inet[%d]->address[%d]: size = %d, data = %u, type = %d\n", i, j, (int)out_addr.sa_len, pin.s_addr, (int)out_addr.sa_family); else PRINTF("inet[%d]->address[%d]: size = %d, data = %s, data addr = %p, type = %d\n", i, j, (int)out_addr.sa_len, out_addr.sa_data, out_addr.sa_data, (int)out_addr.sa_family); } else if (err == 40) { if ((err = ifaddr_address(addresses[j], &out_addr, 20)) == 0) { if (inet_aton(out_addr.sa_data, &pin)) PRINTF("inet[%d]->address[%d]: size = %d, data = %u, type = %d\n", i, j, (int)out_addr.sa_len, pin.s_addr, (int)out_addr.sa_family); else PRINTF("inet[%d]->address[%d]: size = %d, data = %s, data addr = %p, type = %d\n", i, j, (int)out_addr.sa_len, out_addr.sa_data, out_addr.sa_data, (int)out_addr.sa_family); } else PRINTF("inet[%d]->address[%d]: still fail with larger sa_len, err = %d\n", i, j, err); } else PRINTF("inet[%d]->address[%d]: NULL sock address, err = %d\n", i, j, err); if ((err = ifaddr_dstaddress(addresses[j], &out_addr, sizeof(struct sockaddr))) == 0) { if (inet_aton(out_addr.sa_data, &pin)) PRINTF("inet[%d]->dstaddress[%d]: size = %d, data = %u, type = %d\n", i, j, (int)out_addr.sa_len, pin.s_addr, (int)out_addr.sa_family); else PRINTF("inet[%d]->dstaddress[%d]: size = %d, data = %s, data addr = %p, type = %d\n", i, j, (int)out_addr.sa_len, out_addr.sa_data, out_addr.sa_data, (int)out_addr.sa_family); } else PRINTF("inet[%d]->dstaddress[%d]: NULL sock dst address, err = %d\n", i, j, err); if ((err = ifaddr_netmask(addresses[j], &out_addr, sizeof(struct sockaddr))) == 0) { if (inet_aton(out_addr.sa_data, &pin)) PRINTF("inet[%d]->netmask[%d]: size = %d, data = %u, type = %d\n", i, j, (int)out_addr.sa_len, pin.s_addr, (int)out_addr.sa_family); else PRINTF("inet[%d]->netmask[%d]: size = %d, data = %s, data addr = %p, type = %d\n", i, j, (int)out_addr.sa_len, out_addr.sa_data, out_addr.sa_data, (int)out_addr.sa_family); } else PRINTF("inet[%d]->netmask[%d]: NULL netmask address, err = %d\n", i, j, err); } } } } And this is the output that I got: dc 01aaec60 inet[0]->address[0]: still fail with larger sa_len, err = 45 dd 01aaec60 inet[0]->dstaddress[0]: NULL sock dst address, err = 45 de 01aaec60 inet[0]->netmask[0]: size = 11, data = , data addr = 0xce1b9e2, type = 0 e1 01aaec60 inet[0]->address[1]: still fail with larger sa_len, err = 45 e2 01aaec60 inet[0]->dstaddress[1]: NULL sock dst address, err = 45 e3 01aaec60 inet[0]->netmask[1]: NULL netmask address, err = 40 e6 01aaec60 inet[0]->address[2]: size = 16, data = , data addr = 0xce1b9e2, type = 2 e7 01aaec60 inet[0]->dstaddress[2]: size = 16, data = , data addr = 0xce1b9e2, type = 2 e8 01aaec60 inet[0]->netmask[2]: size = 7, data = , data addr = 0xce1b9e2, type = 2 eb 01aaec60 inet[0]->address[3]: still fail with larger sa_len, err = 45 ec 01aaec60 inet[0]->dstaddress[3]: NULL sock dst address, err = 45 ed 01aaec60 inet[0]->netmask[3]: NULL netmask address, err = 40 f6 01aaec60 inet[1]->address[0]: still fail with larger sa_len, err = 45 f7 01aaec60 inet[1]->dstaddress[0]: NULL sock dst address, err = 45 f8 01aaec60 inet[1]->netmask[0]: size = 11, data = , data addr = 0xce1b9e2, type = 0 fb 01aaec60 inet[1]->address[1]: still fail with larger sa_len, err = 45 fc 01aaec60 inet[1]->dstaddress[1]: NULL sock dst address, err = 45 fd 01aaec60 inet[1]->netmask[1]: NULL netmask address, err = 40 100 01aaec60 inet[1]->address[2]: size = 16, data = , data addr = 0xce1b9e2, type = 2 101 01aaec60 inet[1]->dstaddress[2]: size = 16, data = , data addr = 0xce1b9e2, type = 2 102 01aaec60 inet[1]->netmask[2]: size = 7, data = , data addr = 0xce1b9e2, type = 2 Anyone has any idea why the sa_data field is always empty?
