recursive_timed_mutex::try_lock_until Method

Attempts to obtain ownership of the mutex without blocking.

template<class Clock, class Duration>
   bool try_lock_for(const chrono::time_point<Clock, Duration>& Abs_time);
bool try_lock_until(const xtime *Abs_time);

Parameters

  • Abs_time
    A point in time that specifies the threshold after which the method no longer attempts to obtain ownership of the mutex.

Return Value

true if the method successfully obtains ownership of the mutex or if the calling thread already owns the mutex; otherwise, false.

Remarks

If the calling thread already owns the mutex, the method immediately returns true, and the previous lock remains in effect.
