menu_win(3X)                                                menu_win(3X)

NAME

       menu_win - make and break menu window and subwindow associations

SYNOPSIS

       #include <menu.h>

       int set_menu_win(MENU *menu, WINDOW *win);
       WINDOW *menu_win(const MENU *menu);

       int set_menu_sub(MENU *menu, WINDOW *sub);
       WINDOW *menu_sub(const MENU *menu);

       int scale_menu(const MENU *menu, int *rows, int *columns);

DESCRIPTION

       Every menu has an associated pair of curses windows.  The menu
       window displays any title and border associated with the window;
       the menu subwindow displays the items of the menu that are
       currently available for selection.

       The first four functions get and set those windows.  It is not
       necessary to set either window; by default, the driver code uses
       stdscr for both.

       In the set_ functions, window argument of NULL is treated as
       though it were stsdcr.  A menu argument of NULL is treated as a
       request to change the system default menu window or subwindow.

       The function scale_menu returns the minimum size required for the
       subwindow of menu.

RETURN VALUE

       Routines that return pointers return NULL on error.  Routines
       that return an integer return one of the following error codes:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno(3)).

       E_BAD_ARGUMENT
            Routine detected an incorrect or out-of-range argument.

       E_POSTED
            The menu has already been posted.

       E_NOT_CONNECTED
            No items are connected to the menu.

SEE ALSO

       curses(3X), curs_variables(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.
