template<class Clock,class Duration> bool try_lock_until(conststd::chrono::time_point<Clock, Duration>& timeout_time);		(since C++11)

Tries to lock (i.e., takes ownership of) the associated mutex. Blocks until specifiedtimeout_time has been reached or the lock is acquired, whichever comes first. On successful lock acquisition returnstrue, otherwise returnsfalse. May block for longer thantimeout_time until has been reached.

Effectively callsmutex()->try_lock_until(timeout_time).

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

Clock must meet theClock requirements.The program is ill-formed ifstd::chrono::is_clock_v<Clock> isfalse.(since C++20)

[edit]Parameters

timeout_time

maximum time point to block until

[edit]Return value

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

[edit]Exceptions

Any exceptions thrown bymutex()->try_lock_until(timeout_time).

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

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