Class Description

                                                                      
 TMonitor                                                             
                                                                      
 This class monitors activity on a number of network sockets.         
 The actual monitoring is done by TSystem::DispatchOneEvent().        
 Typical usage: create a TMonitor object. Register a number of        
 TSocket objects and call TMonitor::Select(). Select() returns the    
 socket object which has data waiting. TSocket objects can be added,  
 removed, (temporary) enabled or disabled.                            
                                                                      

 Create a monitor object.

 Cleanup the monitor object. Does not delete socket being monitored.

 Add socket to the monitor's active list. If interest=kRead then we
 want to monitor the socket for read readiness, if interest=kWrite
 then we monitor the socket for write readiness, if interest=kRead|kWrite
 then we monitor both read and write readiness.

 Remove a socket from the monitor.

 Remove all sockets from the monitor.

 Activate a de-activated socket.

 Activate all de-activated sockets.

 De-activate a socket.

 De-activate all activated sockets.

 Return pointer to socket for which an event is waiting.

 Return pointer to socket for which an event is waiting. Wait a maximum
 of timeout milliseconds. If return is due to timeout it returns
 (TSocket *)-1.

 Called by TSocketHandler::Notify() to signal which socket is ready
 to be read. User should not call this routine. The ready socket will
 be returned via the Select() user function.

 Return number of sockets in the active list.

 Return number of sockets in the de-active list.

 Returns a list with all active sockets. This list must be deleted
 by the user. DO NOT call Delete() on this list as it will delete
 the sockets that are still being used by the monitor.

 Returns a list with all de-active sockets. This list must be deleted
 by the user. DO NOT call Delete() on this list as it will delete
 the sockets that are still being used by the monitor.
