NAME
set_menu_items, menu_items, item_count - make and break connections between items and menus
SYNOPSIS
#include <menu.h>

int set_menu_items(MENU *menu, ITEM **items);

ITEM **menu_items(const MENU *menu);

int item_count(const MENU *menu);

DESCRIPTION
The function set_menu_items changes the item pointer array of the given menu. The array must be terminated by a NULL.

The function menu_items returns the item array of the given menu.

The function item_count returns the count of items in menu.

RETURN VALUE
The function menu_items returns a pointer (which may be NULL). It does not set errno.

The function item_count returns ERR (the general curses error return value) if its menu parameter is NULL.

The function set_menu_items returns one of the following codes on error:

5 E_OK The routine succeeded.

5 E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument.

5 E_NOT_CONNECTED No items are connected to the menu.

5 E_POSTED The menu is already posted.

5 E_SYSTEM_ERROR System error occurred (see errno(3)). .

SEE ALSO
curses(3X), menu(3X).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.

The SVr4 menu library documentation specifies the item_count error value as -1 (which is the value of ERR).
