You can't.
std::threads are not interruptible. You can use boost::thread which offers this feature.
Boost does this by defining "interrupt points" on which the thread will end if it is interrupted and reaches such a point.
Nevertheless, most of the time thinking about a redesign might be the cleanest and easiest way to reach what you are trying to achieve.
If you are still looking for a C++11 implementation of interruptible threads checkout out Anthony Williams (owner of boost thread) book "C++ Concurrency in Action". He goes through a basic implementation of how such a thing can be achieved.
std::thread::native_handle gives you access to the platform specific underlying thread handle which might support interrupting, however this approach makes your code unportable and probably not cleaner in any way.
