As usual with C type declarations, all you need to do is declare the symbol
in the proper context; since getmenu() has type equivalent to func, simply
plug getmenu() in place of func in the declaration used for func:

	int	(*getmenu())();

This is similar to the C library signal() function (which has void basic
type instead of int).  Since your example didn't use the int supposedly
returned by (*func)(), perhaps you too should be using void not int.
