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

Tries to lock the 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.

Parameters

timeout_time

-

maximum time point to block until

Return value

true if the lock was acquired successfully, otherwise false.

Example

This example shows a two minute block

#include <iostream>
#include <ctime>
#include <chrono>
#include <mutex>
 
int main()
{
    std::timed_mutex test;
    test.try_lock();
    auto now=std::chrono::steady_clock::now();
    test.try_lock_until(now+std::chrono::minutes(2));
    std::cout << "hello world";
 
}
