Try this one.  Net people please check!!!

		int (*p)()		p is a pointer to a function returning int.

		(int (*)()) f() f is a func returning a pointer to a func 
						returning int.


You are much better off building your type via typedefs!!

typedef int (*pfint)();	/* ptr to function returning int */

pfint f();	/* declares f as func returning ptr to func returning int */
