NAME         top

       get menu options

SYNOPSIS         top

       #include <menu.h>

       int set_menu_opts(MENU *menu, Menu_Options opts);
       Menu_Options menu_opts(const MENU *menu);

       int menu_opts_off(MENU *menu, Menu_Options opts);

DESCRIPTION         top

       The function set_menu_opts sets all the given menu's option bits
       (menu option bits may be logically-OR'ed together).

       The function menu_opts_on turns on the given option bits, and
       leaves others alone.

       The function menu_opts_off turns off the given option bits, and
       leaves others alone.

       The function menu_opts returns the menu's current option bits.

       The following options are defined (all are on by default):

       O_ONEVALUE
            Only one item can be selected for this menu.

       O_SHOWDESC
            Display the item descriptions when the menu is posted.

       O_ROWMAJOR
            Display the menu in row-major order.

       O_IGNORECASE
            Ignore the case when pattern-matching.

       O_SHOWMATCH
            Move the cursor to within the item name while pattern-
            matching.

       O_NONCYCLIC
            Don't wrap around next-item and previous-item, requests to
            the other end of the menu.

       O_MOUSE_MENU
            If user clicks with the mouse and it does not fall on the
            currently active menu, push KEY_MOUSE and the MEVENT data
            back on the queue to allow processing in another part of the
            calling program.
