menu_opts - set and get menu options


SYNOPSIS

       #include <menu.h>
       int set_menu_opts(MENU *menu, OPTIONS opts);
       int menu_opts_on(MENU *menu, OPTIONS opts);
       int menu_opts_off(MENU *menu, OPTIONS opts);
       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  pat-
            tern-matching.

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


RETURN VALUE

       Except for menu_opts, each routine returns one of the fol-
       lowing:

       E_OK The routine succeeded.

            System error occurred (see errno).

       E_POSTED
            The menu is already posted.
