alert - Displays a popup alert box. Allegro game programming library.

       Displays  a  popup alert box, containing three lines of text (s1-s3), and with either one or two buttons.
       The text for these buttons is passed in `b1' and `b2' (`b2' may be NULL), and the keyboard  shortcuts  in
       `c1' and `c2' as ASCII value. Example:

          if (!exists(CONFIG_FILE))
             alert(CONFIG_FILE, "not found.", "Using defaults.",
                   "&Continue", NULL, 'c', 0);

       Returns  1 or 2 depending on which button was clicked. If the alert is dismissed by pressing ESC when ESC
       is not one of the keyboard shortcuts, it treats it as a click on the second button  (this  is  consistent
       with the common "Ok", "Cancel" alert).
