SEMGIVE releases a semaphore. If the semaphore was taken before, it is marked as a free semaphore and any task may take it by using the SEMTAKE command. If the semaphore was already free, its status does not change. If a task takes the semaphore using SEMTAKE, the semaphore may be released by the same task or by any task in the system (even from the command line).
