gui_menu_draw_menu(3alleg4) Allegro manual gui_menu_draw_menu(3alleg4)NAME
gui_menu_draw_menu, gui_menu_draw_menu_item - Hooks to modify the appearance of menus. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
extern void (*gui_menu_draw_menu)(int x, int y, int w, int h);
extern void (*gui_menu_draw_menu_item)(MENU *m, int x, int y, int w,
int h, int bar, int sel);
DESCRIPTION
If set, these functions will be called whenever a menu needs to be drawn, so you can change how menus look.
gui_menu_draw_menu() is passed the position and size of the menu. It should draw the background of the menu onto screen.
gui_menu_draw_menu_item() is called once for each menu item that is to be drawn. bar will be set if the item is part of a top-level hori-
zontal menu bar, and sel will be set if the menu item is selected. It should also draw onto screen.

d_menu_proc(3alleg4) Allegro manual d_menu_proc(3alleg4)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.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

In this case will the 1 gb of heap memory be returned... (9 Replies)

Does this mean that it will run on any shell ?
