## 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
                The menu is already posted.

## PORTABILITY

           ported on Version 7 or BSD versions.
