Depends on how foo was declared:

	void foo(int *a);
		It's an array of ints.
	void foo(char *a);
		It's an array of chars.
	void foo(double *a);
		It's an array of doubles.
	struct x { int i; char c; float f; double d; };
	void foo(struct x *a);
		It's a pointer to an int, a char, a float, and a double.
This one's kinky:
	void foo(struct x a);

Extra credit question: how does that differ from:
	void foo(int i, char c, float f, double d);
		And called with foo(1, 2, 3, 4);
