Socket::Ifaddr represents a result of getifaddrs() function.
Returns the address of ifaddr. nil is returned if address is not available in ifaddr.
static VALUE ifaddr_addr(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); if (ifa->ifa_addr) return rsock_sockaddr_obj(ifa->ifa_addr, rsock_sockaddr_len(ifa->ifa_addr)); return Qnil; }
Returns the broadcast address of ifaddr. nil is returned if the flags doesn’t have IFF_BROADCAST.
static VALUE ifaddr_broadaddr(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); if ((ifa->ifa_flags & IFF_BROADCAST) && ifa->ifa_broadaddr) return rsock_sockaddr_obj(ifa->ifa_broadaddr, rsock_sockaddr_len(ifa->ifa_broadaddr)); return Qnil; }
Returns the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.
static VALUE ifaddr_dstaddr(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); if ((ifa->ifa_flags & IFF_POINTOPOINT) && ifa->ifa_dstaddr) return rsock_sockaddr_obj(ifa->ifa_dstaddr, rsock_sockaddr_len(ifa->ifa_dstaddr)); return Qnil; }
Returns the flags of ifaddr.
static VALUE ifaddr_flags(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); return IFAFLAGS2NUM(ifa->ifa_flags); }
Returns the interface index of ifaddr.
static VALUE ifaddr_ifindex(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); unsigned int ifindex = if_nametoindex(ifa->ifa_name); if (ifindex == 0) { rb_raise(rb_eArgError, "invalid interface name: %s", ifa->ifa_name); } return UINT2NUM(ifindex); }
Returns a string to show contents of ifaddr.

Returns the interface name of ifaddr.
static VALUE ifaddr_name(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); return rb_str_new_cstr(ifa->ifa_name); }
Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.
static VALUE ifaddr_netmask(VALUE self) { struct ifaddrs *ifa = get_ifaddrs(self); if (ifa->ifa_netmask) return rsock_sockaddr_obj(ifa->ifa_netmask, rsock_sockaddr_len(ifa->ifa_netmask)); return Qnil; }
