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

DESCRIPTION

The menu_items() function returns a pointer to an array of item pointers that represent the menu items currently attached to the given menu. Apart from using new_menu() (see menu_new(3)) menu items may be attached to a menu by calling set_menu_items() any items currently attached to the menu will be detached and the NULL terminated array of new items will be attached to the menu.

RETURN VALUES

Any function returning a string pointer will return NULL if an error occurs. Functions returning an integer will return one of the following:

E_OK

The function was successful.

E_POSTED

The menu is already posted.

E_CONNECTED
