signalmanager.h File Reference

The class for SMPSignalManager, the watchdog object for all signal_handler thread in the system. This defines a watchdog, which will create threads for each signal_handler thread of a filter in the system. Each filter can have at most 1 signal_handler thread, and this watchdog will create another thread for each signal_handler, thus ordering it to watch the thread for timed-out execution of a signal.
