       al_show_native_message_box - Allegro 5 API

	      #include <allegro5/allegro_native_dialog.h>

	      int al_show_native_message_box(ALLEGRO_DISPLAY *display,
		 char const *title, char const *heading, char const *text,
		 char const *buttons, int flags)

       Show a native GUI message box.  This can	be used	for example to display
       an error	message	if creation of an initial display fails.  The  display
       may  be	NULL,  otherwise the given display is treated as the parent if

       The message box will have a single "OK" button and use the style	infor-
       mative  dialog boxes usually have on the	native system.	If the buttons
       parameter is not	NULL, you can instead specify the  button  text	 in  a
       string, with buttons separated by a vertical bar	(|).

	      The  message  is a warning.  This	may cause a different icon (or
	      other effects).  ALLEGRO_MESSAGEBOX_ERROR
       The message is an error.	 ALLEGRO_MESSAGEBOX_QUESTION
       The message is a	question.  ALLEGRO_MESSAGEBOX_OK_CANCEL
       Instead of the "OK" button also display a cancel	 button.   Ignored  if
       buttons is not NULL.  ALLEGRO_MESSAGEBOX_YES_NO
       Instead	of the "OK" button display Yes/No buttons.  Ignored if buttons
       is not NULL.

       al_show_native_message_box(3) may be called without Allegro  being  in-
       stalled.	  This	is useful to report an error to	initialise Allegro it-


       o 0 if the dialog window	was closed without activating a	button.

       o 1 if the OK or	Yes button was pressed.

       o 2 if the Cancel or No button was pressed.

       If buttons is not NULL, the number of the pressed button	 is  returned,
       starting	with 1.

       If  a  message  box could not be	created	then this returns 0, as	if the
       window was dismissed without activating a button.


		button = al_show_native_message_box(
		   "Are	you sure?",
		   "If you click yes then you are confirming that \"Yes\""
		   "is your response to	the query which	you have"
		   "generated by the action you	took to	open this"
		   "message box.",
