    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 simultaneously 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.
