NAME
mitem_opts - set and get menu item options
SYNOPSIS
#include <menu.h>
int set_item_opts(ITEM *item, Item_Options opts);
int item_opts_on(ITEM *item, Item_Options opts);
int item_opts_off(ITEM *item, Item_Options opts);
Item_Options item_opts(const ITEM *item);
DESCRIPTION
The function set_item_opts sets all the given item's option bits (menu
option bits may be logically-OR'ed together).
The function item_opts_on turns on the given option bits, and leaves
others alone.
The function item_opts_off turns off the given option bits, and leaves
others alone.
The function item_opts returns the item's current option bits.
There is only one defined option bit mask, O_SELECTABLE. When this is
on, the item may be selected during menu processing. This option defaults
to on.
RETURN VALUE
Except for item_opts, each routine returns one of the following:
- E_OK
-
The routine succeeded.
- E_SYSTEM_ERROR
-
System error occurred (see errno).
SEE ALSO

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.
