        # UDPSocket.send

(from ruby core)

    udpsocket.send(mesg, flags, host, port)  => numbytes_sent
    udpsocket.send(mesg, flags, sockaddr_to) => numbytes_sent
    udpsocket.send(mesg, flags)              => numbytes_sent

Sends *mesg* via *udpsocket*.

*flags* should be a bitwise OR of Socket::MSG_* constants.

    u1 = UDPSocket.new
    u1.bind("127.0.0.1", 4913)

    u2 = UDPSocket.new
    u2.send "hi", 0, "127.0.0.1", 4913

    mesg, addr = u1.recvfrom(10)
    u1.send mesg, 0, addr[3], addr[1]

    p u2.recv(100) #=> "hi"
