struct ifaddr is the in-kernel representation of the interface address. In kernel each network interface consists of a linked list of interface addresses, described by ifaddr structures. See man ifnet(9): http://man.freebsd.org/ifnet struct ifaddrs is used in the userland BSD API getifaddrs(3). This interface is used to get interface addresses in userland programs. See how it is used in e.g. ifconfig(8) sources: /usr/src/sbin/ifconfig/ifconfig.c See man getifaddrs(3): http://man.freebsd.org/getifaddrs -- wbr, pluknet _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
