Getting return value from a boost::threaded member function?

Question

I have a worker class like the one below:

class Worker{
public:
  int Do(){
    int ret = 100;
    // do stuff
    return ret;
  }
}

It\'s

Answer 1

I don't think you can get the return value.

Instead, you can store the value as a member of Worker:

class Worker{
public:
  void Do(){
    int ret = 100;
    // do stuff
    m_ReturnValue = ret;
  }
  int m_ReturnValue;
}

And use it like so:

Worker worker;
boost::function th_func = boost::bind(&Worker::Do, &worker);
boost::thread th(th_func);
th.join();
//do something with worker.m_ReturnValue
