menuwin(3X)                                                      menuwin(3X)



NAME
       menuwin - make and break menu window and subwindow associations

SYNOPSIS
       ##include <>
       int setmenuwin(MENU *menu, WINDOW *win);
       WINDOW *menuwin(const MENU *menu);
       int setmenusub(MENU *menu, WINDOW *sub);
       WINDOW *menusub(const MENU *menu);
       int scalemenu(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 NUL is treated as though  it
       were stsdcr.  A menu argument of NUL is treated as a request to change
       the system default menu window or subwindow.

       The function scalemenu returns the minimum size required for the  sub-
       window of menu.

RETURN VALUE
       Routines  that  return  pointers  return  NUL on error.  Routines that
       return an integer return one of the following error codes:

       EOK The routine succeeded.

       ESYSTEMEROR
            System error occurred (see errno).

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

       EPOSTED
            The menu has already been posted.

       ENOTCONECTED
            No items are connected to the menu.

NOTES
       The  header  file  <>  automatically  includes  the  header  file
       <>.

PORTABILITY
       These  routines  emulate the System V menu library.  They were not sup-
       ported on Version 7 or BSD versions.
