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;
  }
}

In addition, you also have some redundant calls to boost::bind() and boost::function(). You can instead do the following:

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

Worker worker;
boost::thread th(worker());//or boost::thread th(boost::ref(worker));

You can do this because Thread's constructor is a convenience wrapper around an internal bind() call. Thread Constructor with arguments
