NAME

menu_items - make and break connections between items and menus

CONTENTS

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:
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

curses(3), menu(3).

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).
