init_menu - Man Page

#include <allegro.h>

MENU_PLAYER *init_menu(MENU *menu, int x, int y);

This function provides lower level access to the same functionality as  do_menu(), but allows you to combine a popup menu with your own program  control structures. It initialises a menu, returning a pointer to a menu player object that can be used with update_menu() and shutdown_menu(). With these functions, you could implement your own version of do_menu() with the lines:

   MENU_PLAYER *player = init_menu(menu, x, y);
   
   while (update_menu(player))
      ;
   
   return shutdown_menu(player);

update_menu(3), shutdown_menu(3), do_menu(3)

MENU_PLAYER(3), shutdown_menu(3), update_menu(3).
