       d_menu_proc - Dialog procedure implementing a menu bar object. Allegro
       game programming library.

       #include <allegro.h>

       int d_menu_proc(int msg, DIALOG *d, int c);

       This object is a menu bar which will drop down child menus when it is
       clicked or if an alt+key corresponding to one of the shortcuts in the
       menu is pressed. It ignores a lot of the fields in the dialog structure,
       in particular the color is taken from the gui_*_color variables, and the
       width and height are calculated automatically (the w and h fields from
       the DIALOG are only used as a minimum size.) The dp field points to an
       array of menu structures: see do_menu() for more information. The top
       level menu will be displayed as a horizontal bar, but when child menus
       drop down from it they will be in the normal vertical format used by
       do_menu(). When a menu item is selected, the return value from the menu
       callback function is passed back to the dialog manager, so your callbacks
       should return D_O_K, D_REDRAW, or D_CLOSE.
