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

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).
