menu_format - set and get menu sizes
#include <menu.h>
int set_menu_format(MENU *menu, int rows, int cols);
void menu_format(const MENU *menu, int *rows, int *cols);
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 con-
straints for the given menu into the storage addressed by
rows and cols.

not supported on Version 7 or BSD versions.
