Socket::Ifaddr
Socket::Ifaddr represents a result of getifaddrs() function.
Public Instance Methods
addr => addrinfo
click to toggle source
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;
}
broadaddr => addrinfo
click to toggle source
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;
}
dstaddr => addrinfo
click to toggle source
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 Qnil;
}
flags => integer
click to toggle source
Returns the flags of ifaddr.
static VALUE
ifaddr_flags(VALUE self)
{
struct ifaddrs *ifa = get_ifaddrs(self);
return IFAFLAGS2NUM(ifa->ifa_flags);
}
ifindex => integer
click to toggle source
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) {

}
return UINT2NUM(ifindex);
}
inspect => string
click to toggle source
Returns a string to show contents of ifaddr.
static VALUE

}
name => string
click to toggle source
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);
}
netmask => addrinfo
click to toggle source
