       Juergen Pfeifer.  Manual pages and adaptation for new curses by Eric S. Raymond.

       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.
