primaryComponentOKToEndSim
void primaryComponentOKToEndSim();
Availability: Component
A primary component that has previous registered using registerAsPrimaryComponent() calls this function to let the simulation know that it is currently OK to end simulation. Simulation will not end until all primary components have called this function.
To change status and prevent simulation end, use primaryComponentDoNoEndSim().
Parameters
- returns None
