al_get_native_text_log_event_source - Allegro 5 API

       Get an event source for a text log window.  The possible events are:

       ALLEGRO_EVENT_NATIVE_DIALOG_CLOSE
              The  window  was requested to be closed, either by pressing the close button or pressing Escape on
              the keyboard.  The user.data1 field will hold a  pointer  to  the  ALLEGRO_TEXTLOG(3alleg5)  which
              generated  the  event.  The user.data2 field will be 1 if the event was generated as a result of a
              key press; otherwise it will be zero.
