type of function

[Supoj Sutanthavibul]

How would one declare a function which returns a pointer to a function
which return void?  To clarify this question, here is an example.  The
question is: what is the type of get_func()?  Or, how would it be declared
in another function that calls it?

	void
	foo1()
	{
		...
		}

	void
	foo2()
	{
		...
		}

	.
	.
	.

	void
	fooN()
	{
		...
		}

	get_func(which)
	int	which;
	{
		if (... which ... ) return(foo1);
		...
		else if (... which ... ) return(fooN);
		}
