Detailed Description

Interface for the service that monitors the occurrences of system signals.

The signal to be monitored have to be declared via the method monitorSignal(). The method gotSignal() can used to check if a signal has been received.

Note that the service is passive, in the sense that it simply keeps track of received signals without performing any action. So it is responsibility of the users to add a check if the signal has been received or not.

signal number

Implemented in Gaudi::Utils::SignalMonitorSvc.

virtual void Gaudi::ISignalMonitor::ignoreSignal

(

int

signum )

[pure virtual]

Ignore future occurrences of the given signal number.

Parameters:

virtual void Gaudi::ISignalMonitor::monitorSignal	(	int	signum,
		bool	propagate = true
	)		[pure virtual]

Add a signal (number) to the list of signals to be monitored.

It possible to choose if a previously installed signal handler should be called or not.

Parameters:

signum,:	signal number
propagate,:	if true (default) an already present signal handler is called, otherwise the signal is stopped in the service.

Implemented in Gaudi::Utils::SignalMonitorSvc.

(

int

signum )

[pure virtual]

Set the flag for the given signal, as if the signal was received.

Parameters:

signum,:

signal number

Implemented in Gaudi::Utils::SignalMonitorSvc.
