template< class Clock, class Duration > bool try_lock_until( const std::chrono::time_point<Clock,Duration>& timeout_time ); | (since C++11) |
Tries to lock the associated mutex. 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_until(timeout_time).
std::system_error is thrown if there is no associated mutex or if the mutex is already locked.

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