### Data Members

        protected:

          ESignals fSignal  Signal to be handled

## Class Description

     TSysEvtHandler

     Abstract base class for handling system events.

TSignalHandler(ESignals sig, Bool_t sync)

Bool_t Notify()

     Notify when signal occurs.

void Add()

     Add signal handler to system signal handler list.

void Remove()

     Remove signal handler from system signal handler list.
