NAME
     mitem_value - set and get menu item values

SYNOPSIS
     #include <menu.h>
     int set_item_value(ITEM *item, bool value);
     bool item_value(const ITEM *item);

DESCRIPTION
     If you turn off  the  menu  option  O_ONEVALUE  (e.g.,  with
     set_menu_opts or menu_opts_off; see menu_opts(3X)), the menu
     becomes multi-valued; that is, more than one item may simul-
     taneously be selected.

     In a multi_valued  menu,  you  can  used  set_item_value  to
     select  the  given  menu  item  (second  argument  TRUE)  or
     deselect it (second argument FALSE).

RETURN VALUE
     The function set_item_value returns one of the following:

     E_OK The routine succeeded.

     E_SYSTEM_ERROR
          System error occurred (see errno).

     E_REQUEST_DENIED
          The menu driver could not process the request.

SEE ALSO
     curses(3X), menu(3X).

NOTES
     The header file <menu.h> automatically includes  the  header
     file <curses.h>.

PORTABILITY
     These routines emulate the System V menu library.  They were
     not supported on Version 7 or BSD versions.
