I get sigseg when try to execute it (ubuntu 16.04, gcc 5.4.0). According to http://man7.org/linux/man-pages/man3/getifaddrs.3.html : "The ifa_addr... .This field may contain a null pointer." Little check for null pointer proposed. Or may be it'll be better with for cycle since two lines of adress = adress->ifa_addr in my proposal.
