sockopt_s_ipv4_multicast_loop(VALUE klass, VALUE value)
{

#if defined(IPPROTO_IP) && defined(IP_MULTICAST_LOOP)

# error IPPROTO_IP or IP_MULTICAST_LOOP is not implemented
#endif
}

Creates a new Socket::Option object for IP_MULTICAST_LOOP.

The size is dependent on the platform.

Example

sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1)
p sockopt.int => 1

p Socket::Option.ipv4_multicast_loop(10)
#=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
