Take a look at this:

main()
{
	int fred(), (*p)();

	p = fred;

	(*p)(10);		/* The right way */
	p(10);			/* This works too */
}

int
fred(x)
...

The (*p)(args) invocation is the K&R standard. p(args) also works on at
least 4 different Unix compilers.

Q: Is p(args) legal, portable C?
Q: Is p(args) preferential to (*p)(args) as it looks neater, compare:
	s->p(args)	(*s->p)(args)

Any thoughts? I've only ever used (*p)()... I only came across p() recently.

Dave.
