void release( std::ptrdiff_t update = 1 );		(since C++20)

Atomically increments the internal counter by the value of update. Any thread(s) waiting for the counter to be greater than ​0​, such as due to being blocked in acquire, will subsequently be unblocked.

This operation strongly happens before invocations of try_acquire that observe the result of the effects.

Preconditions

Both update >= 0 and update <= max() - counter are true, where counter is the value of the internal counter.

Parameters

update

-

the amount to increment the internal counter by

Exceptions

May throw std::system_error.

acquire	decrements the internal counter or blocks until it can (public member function)
try_acquire	tries to decrement the internal counter without blocking (public member function)
try_acquire_for	tries to decrement the internal counter, blocking for up to a duration time (public member function)
try_acquire_until	tries to decrement the internal counter, blocking until a point in time (public member function)
