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
       subwindow 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_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.
