Re: Choosing function parameter types - pointers or objects?

I know this question is a bit vague, but I was wondering about any
rules / guidelines / style issues, for when to use pointers, and when
not to, in your function parameters?

If it's a native type (int, short, long, double, that sort of thing), pass
it in raw unless you need to hack its value. Anything else - structs and
stuff - pass a pointer.

I wouldn't hesitate to pass a *small* structure directly.

We must do something. This is something. Therefore, we must do this.
