std::shared_lock<Mutex>::try_lock_until: std::shared_lock<Mutex>::try_lock_until


std::shared_lock<Mutex>::try_lock_until - std::shared_lock<Mutex>::try_lock_until


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

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.


timeout_time - maximum time point to block until

Return value

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


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

* If there is no associated mutex, std::system_error with an error code of std::errc::operation_not_permitted

* If the mutex is already locked, std::system_error with an error code of std::errc::resource_deadlock_would_occur
