YACSIM Semaphores are used for controlling the interaction of events in the simulator. The following semaphore functions are supported in RSIM:

• SEMAPHORE *NewSemaphore(char *sname, int i)

  This function creates a new semaphore with the name specified in sname and the initial semaphore value i.

• void SemaphoreSignal(SEMAPHORE *sptr)

  This function activates the event at the head of the semaphore queue (added through a previous call to ActivitySchedSema or EventReschedSema). If there is no event, the semaphore value is incremented.
