{
VALUE domain, type, protocol;

args[2] = protocol;
return rsock_sock_s_socketpair(3, args, klass);
}
Creates a pair of sockets connected to each other.
type should be a socket type such as: :STREAM, :DGRAM, :RAW, etc.
protocol should be a protocol defined in the domain. 0 is default protocol for the domain.
Example
s1, s2 = UNIXSocket.pair s1.send "a", 0 s1.send "b", 0 p s2.recv(10) #=> "ab"
