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

SYNOPSIS
       #include <allegro.h>


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

DESCRIPTION
       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.
