std::shared_lock::try_lock_until
From cppreference.com
< cpp | thread | 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.

[edit] Exceptions
- 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
