How to stop/interrupt a boost::thread?

I create a thread in a function,and in another function,I wanna stop this thread. I have tried like this:

class Server
{
private:
     boost::thread* mPtrThread;
...

public:
     void createNewThread()
     {
        boost::thread t(...);
        mPtrThread = &t;
     }


     void stopThread()
     {
        mPtrThread->interrupt();
     }
}

But it's not work.How could I stop the thread?

First of all, in createNewThread() you declare a boost::thread t in a local scope and assign its pointer to the class member mPtrThread. After createNewThread() finishes, t is destroyed and mPtrThread would hold an illegal pointer.

I'd rather use something like mPtrThread = new boost::thread(...);

If you want to use interrupt() you should define interruption points. Thread will be interrupted after calling interrupt() as soon as it reaches one of interruption points.
