NAME
       mitem_value - set(7,n,1 builtins) and get menu(3x,n,n tk_menuSetFocus) 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(3x,n,n tk_menuSetFocus) option O_ONEVALUE (e.g., with set_menu_opts or
       menu_opts_off; see menu_opts(3X)), the menu(3x,n,n tk_menuSetFocus) becomes multi-valued;  that
       is, more than one item may simultaneously be selected.

       In a multi_valued menu(3x,n,n tk_menuSetFocus), you can used set_item_value to select(2,7,2 select_tut) the given
       menu(3x,n,n tk_menuSetFocus) 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(8,n) occurred (see errno).

       E_REQUEST_DENIED
            The menu(3x,n,n tk_menuSetFocus) driver could not process the request.

SEE ALSO

NOTES
       The  header  file(1,n)  <menu.h>  automatically  includes  the  header  file(1,n)
       <curses.h>.

       ported on Version 7 or BSD versions.
