dbaui::OAsynchronousLink Class Reference

handles asynchronous links which may be called in multi-threaded environments If you use an instance of this class as member of your own class, it will handle several crucial points for you (for instance the case that somebody posts the event while another thread tries to delete this event in the destructor of the class).
