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 sub-
       window  displays	the items of the menu that are currently available for
       selection.

       The first four functions	get and	set those windows.  It is  not	neces-
       sary  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  sub-
       window of menu.

RETURN VALUE
       Routines	 that return pointers return NULL on error.  Routines that re-
       turn an integer return one of the following error codes:

       E_OK The	routine	succeeded.

       E_SYSTEM_ERROR
	    System error occurred (see errno).

       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.

       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 sup-
       ported on Version 7 or BSD versions.
