Detailed Description

Class to manage real-time events (signals and alarms)

Member Function Documentation

void SST::RealTimeManager::notifySignal ( )

Simulation run loop calls this when a signal has been received from the OS.

One or more of the sig_X_from_os_ vars will be non-zero.

Serial - this executes the relevant signal handler(s) Parallel - this saves the signals until the next global sync
