NAME
       menu_format - set and get menu sizes

SYNOPSIS
       #include <menu.h>
       int set_menu_format(MENU *menu, int rows, int cols);
       void menu_format(const MENU *menu, int *rows, int *cols);

DESCRIPTION
       The function set_menu_format sets the maximum display size of the given
       menu.  If this size is too small to display all menu  items,  the  menu
       will  be made scrollable. If this size is larger than the menus subwin-
       dow and  the  subwindow  is  too  small  to  display  all  menu  items,
       post_menu() will fail.

       The  default format is 16 rows, 1 column.  Calling set_menu_format with
       a null menu pointer will change this default.  A  zero  row  or  column
       argument  to  set_menu_format is interpreted as a request not to change
       the current value.

       The function menu_format returns the maximum-size constraints  for  the
       given menu into the storage addressed by rows and cols.

RETURN VALUE
       These routines returns one of the following:

       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 is already posted.

       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  sup-
       ported on Version 7 or BSD versions.
