// 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. //
// //
