function TUDPSocket.IsConnected(ALocalAddress,ARemoteAddress:Pointer; ALocalPort,ARemotePort:Word; ABroadcast:Boolean):Boolean;

Description: Check if this UDP Socket is Connected to the Host specified by RemoteAddress/Port

Note	A connected Socket will have a Bound LocalAddress/Port and a Connected RemoteAddress/Port

function TUDPSocket.IsListening(ALocalAddress,ARemoteAddress:Pointer; ALocalPort,ARemotePort:Word; ABroadcast:Boolean):Boolean;

Description: Check if this UDP Socket is Listening on the LocalAddress/Port specified

Note	A listening Socket may or may not have a Bound LocalAddress/Port and will have a default (INADDR_ANY/IPPORT_ANY) RemoteAddress/Port
