mitem_value(3)      UNIX Programmer's Manual       mitem_value(3)

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(3)), 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(3), menu(3).

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.
