Remarks
  • This function is equivalent to the following syntax of EventChange:
    EventChange(<Event>, eventOpen)
  • For an automatic event: A single thread is processed by the event.
    The event is automatically closed once the thread is processed.
    • Pending threads: If there is no pending thread, the event remains open until the next thread, then it is closed.
    • New threads: The new threads are added to the pending queue.
  • For a manual event: The event is opened.
    • Pending threads: All the pending threads are processed.
    • New threads: If other threads arrive while the event is still open, they are processed.
