# std::counting_semaphore<LeastMaxValue>::~counting_semaphore

From cppreference.com
< cpp‎ | thread‎ | counting semaphore

~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.
