std::shared_lock
 
template< class Clock, class Duration >
bool try_lock_until( const std::chrono::time_point<Clock,Duration>& timeout_time );
 (since C++14)

Tries to lock the associated mutex in shared mode. Blocks until specified timeout_time has been reached or the lock is acquired, whichever comes first. On successful lock acquisition returns true, otherwise returns false. May block for longer than until timeout_time has been reached.

Effectively calls mutex()->try_lock_shared_until(timeout_time)

std::system_error is thrown if there is no associated mutex or if the mutex is already locked.

Parameters

timeout_time - maximum time point to block until

Return value

true if the ownership of the mutex has been acquired successfully, false otherwise.

Exceptions

  • Any exceptions thrown by mutex()->try_lock_shared_for(timeout_time)
