I used to have a problem deciding how to keep track of
IN and OUT arguments in functions. Rather than bothering
to clutter up prototypes with names, I came up with this
simple technique:

	for
		anyfunction(IN * A, IN * B, IN * C, OUT * A)

Variables used as input to the given function will be sent
first, in alphabetical order by type. Output variables will be
sent next, alphabetically by type.

Thus,
	str->dup(char *, char ** );

Even without the second indirection giving us an obvious
clue, we know that the first variable is input and the second
is output.

Because I stick to this as a strict part of my API, I never have
to check the source to remind myself what I'm doing.

Just thought I'd give my two cents.
