NAME

       set_menu_opts,  menu_opts_on,  menu_opts_off,  menu_opts  - set and get
       menu options


SYNOPSIS

       #include <menu.h>
       int set_menu_opts(MENU *menu, Menu_Options opts);
       int menu_opts_on(MENU *menu, Menu_Options opts);
       int menu_opts_off(MENU *menu, Menu_Options opts);
       Menu_Options menu_opts(const MENU *menu);


DESCRIPTION

       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  cur-
            rently active menu, push KEY_MOUSE and the MEVENT data back on the
            queue to allow processing in another part of the calling program.


RETURN VALUE

       Except for menu_opts, each routine returns one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

       E_POSTED
