Hi,

first, thanks a lot for the suggestion!
The Init function was an example. My real class is a RS232 wrapper. I
have to start a thread to continuous reading from ports, but only when
the user call the open() method.
I need the thread has a class scope because in the close() method where
I close the thread and I call thread.join()

void SerialPort::reading()
{
  while (!_stoprequested) { reading.... }
}

bool SerialPort::open(void)
{
    try {
      _thread.reset(new boost::thread( boost::bind(&SerialPort::reading,
this));
    } catch (boost::thread_resource_error e) {
      // Failed to create the new thread
      return false;
    }
}

bool SerialPort::close(void)
{
  if (m_serial_port.IsOpen()){
    // If the port is open, then the reading thread is
    _stoprequested = true;
    try{
      _thread.join();
    } catch (boost::thread_interrupted e) {
      //The thread is already stopped..do nothing
    }
    m_serial_port.Close();
  }
  return true;
};

So I think the pointer solution is good!

Thanks again.
Daniele.
