Class Description

                                                                      
 TSysEvtHandler                                                       
                                                                      
 Abstract base class for handling system events.                      
                                                                      

 Create a file descriptor event handler. If mask=kRead then we
 want to monitor the file for read readiness, if mask=kWrite
 then we monitor the file for write readiness, if mask=kRead|kWrite
 then we monitor both read and write readiness.

 Notify when event occured on descriptor associated with this handler.

 Notify when something can be read from the descriptor associated with
 this handler.

 Notify when something can be written to the descriptor associated with
 this handler.

 True if handler is interested in read events.

 True if handler is interested in write events.

 Add file event handler to system file handler list.

 Remove file event handler from system file handler list.
