You ask how ifconfig does IP setting, right? Please see line 114:
ioctl(4, SIOCGIFCONF, {200, {{"lo", {AF_INET,
inet_addr("127.0.0.1")}}, {"eth0", {AF_INET,
inet_addr("192.168.1.197")}}, {"virbr0", {AF_INET,
inet_addr("192.168.122.1")}}, {"vmnet1", {AF_INET,
inet_addr("192.168.205.1")}}, {"vmnet8", {AF_INET,
inet_addr("192.168.43.1")}}}}) = 0
#
ioctl(5, SIOCGIFFLAGS, {ifr_name="eth0",
ifr_flags=IFF_UP|IFF_BROADCAST|IFF_RUNNING|IFF_MULTICAST}) = 0
It's ioctl..
