    ~counting_semaphore();
    		(since C++20)

    Destroys the counting_semaphore object.

    Notes

    It is only safe to invoke the destructor if all threads have been notified. The programmer must ensure that no threads attempt to wait on *this once the destructor has been started. The destructor does not notify and release any waiting threads.
