NAME
items - 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 VALUES
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: E_OK The routine succeeded. E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. E_NOT_CONNECTED No items are connected to the menu. E_POSTED The menu is already posted. E_SYSTEM_ERROR System error occurred (see errno). SEE ALSO
ncurses(3NCURSES), menu(3MENU). 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). AUTHORS
Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S. Raymond. items(3MENU)
