NAME

       set_menu_format, 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_POSTED
            The menu is already posted.

       E_NOT_CONNECTED
            No items are connected to the menu.

PORTABILITY

       These routines emulate the System V menu library.  They were not supported on Version 7 or BSD versions.
