NAME

       menu_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 NULL on error.

       The function item_count returns ERR (the general curses error return value) on error.

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

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

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

       E_POSTED
	    The menu is already posted.

       E_NOT_CONNECTED
	    No items are connected to the menu.

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).
