Miscellaneous Library Functions                      menu_win(3X)



NAME
     menu_win - make and break menu window and subwindow associa-
     tions

SYNOPSIS
     #include 
     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.   Rou-
     tines  that  return  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.
