Creates a new Socket::Option object for IP_MULTICAST_TTL.
The size is dependent on the platform.
p Socket::Option.ipv4_multicast_ttl(10) #=> #<Socket::Option: INET IP MULTICAST_TTL 10>
Returns the ipv4_multicast_ttl data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_ttl(10) p sockopt.ipv4_multicast_ttl => 10
Creates a new Socket::Option object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
