Thanks a lot Igor.
Only one thing.. Is there a way to retrieve a work object from the
io_service?

Now I done it like:

EXTERN_C EUROATLIB_API MyObjHandl CALL GetMyObj()
{
  ...
  p_work = new boost::asio::io_service::work(io_service);
  // create the new object
  MyObj  pMyObj = new MyObj(io_service);
  pMyObj->io_work_ptr = p_work;
  return pMyObj;
}

But I would like to hide the assignment doing it automatically inside my
MyObj which take an io_service ref in the constructor.

Thanks!
Daniele.
