MENU_POST(3)

NAME
post_menu, unpost_menu - post (draw) or unpost a menu

LIBRARY
libmenu

SYNOPSIS
#include <menu.h>
int
post_menu(MENU *menu);
int
unpost_menu(MENU *menu);

DESCRIPTION
The post_menu() function causes the menu to be drawn on the screen. Any functions defined by either set_menu_init() or set_item_init() (see menu_hook(3)) are called before the menu is placed on the screen. The unpost_menu() does the opposite, it removes a menu from the screen. Any functions defined by both set_menu_term() and set_item_term() (see menu_hook(3)) are called prior to the menu's removal.

RETURN VALUES
The functions return one of the following error values:

E_OK
    The function was successful.
E_SYSTEM_ERROR
    There was a system error during the call.
E_BAD_ARGUMENT
    One or more of the arguments passed to the function was incorrect.
E_POSTED
    The menu is already posted.
E_BAD_STATE
    The function was called from within an initialization or termination routine.
E_NO_ROOM
    The menu does not fit within the subwindow.
E_NOT_CONNECTED
    The item is not connected to a menu.
