template< class Rep, class Period > bool try_acquire_for( const std::chrono::duration<Rep, Period>& rel_time ); | (since C++20) |
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.
(none).
| rel_time | - | the minimum duration the function must wait for it to fail |
true if it decremented the internal counter, otherwise false.
May throw std::system_error or a timeout-related exception.
In practice the function may take longer than rel_time to fail.

| tries to decrement the internal counter without blocking (public member function) |
|
| tries to decrement the internal counter, blocking until a point in time (public member function) |
