    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

    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.
