Detailed Description

This class represents a socket for sending and receiving datagram packets.

Constructor & Destructor Documentation

DatagramSocket

(

)

Constructs a datagram socket and binds it to any available port on the local host machine.

DatagramSocket

(

int

port

)

Constructs a datagram socket and binds it to the specified port on the local host machine.

DatagramSocket	(	int	port,
		InetAddress	laddr
	)

Creates a datagram socket, bound to the specified local address.

~DatagramSocket

(

)

ensure the socket is closed.
