Detailed Description

Signal handling master thread in a multi-threaded application

Note: Before starting the SignalMaster one has to block all signals in all threads.

Constructor & Destructor Documentation

SignalMaster ( )

default

Create a null signal master.

SignalMaster	(	const Channel< Signal > &	signals,
		const SignalSet &	shutdownSet = defaultShutdownSignals() )

explicit

Create a new signal master thread.

Parameters

signals	Channel which transmits the received system signals
shutdownSet	Signals that cause the shutdown of the signal master

void start ( )

Start the signal master thread.

void wait ( )

Wait for termination of the signal master thread.

void kill ( Signal signal = Signal::Terminate )

Send signal to the signal master thread.
