std::counting_semaphore<LeastMaxValue>::try_acquire_for

Tries to atomically decrement the internal counter by 1 if it is greater than 0; otherwise blocks until it is greater than 0 and can successfully decrement the internal counter, or the rel_time duration has been exceeded.

# Declarations

template< class Rep, class Period >
bool try_acquire_for( const std::chrono::duration<Rep, Period>& rel_time );

(since C++20)

# Parameters

# Return value

true if it decremented the internal counter, otherwise false.

# Notes

In practice the function may take longer than rel_time to fail.
