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.

E_OK The routine succeeded.
E_SYSTEM_ERROR

SEE ALSO curses(3X), menu(3X).
NOTES
