std::counti...acquire_for(3) C++ Standard Libary std::counti...acquire_for(3) NAME std::counting_semaphore::try_acquire_for - std::counting_semaphore::try_ac- quire_for Synopsis template< class Rep, class Period > bool try_acquire_for( const std::chrono::duration<Rep, Period>& (since C++20) rel_time ); 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 decre- ment the internal counter, or the rel_time duration has been exceeded. Preconditions (none) Parameters rel_time - the minimum duration the function must wait for it to fail Return value true if it decremented the internal counter, otherwise false. Exceptions May throw std::system_error or a timeout-related exception. Notes In practice the function may take longer than rel_time to fail.
