NAME

post_menu, unpost_menu — post (draw) or unpost a menu

LIBRARY

Curses Menu Library (libmenu, -lmenu)

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.
