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?


You'd have the measure the efficiency of:

(1) Passing the object by value (thus copying it in the process).

and

(2) Passing its address, and dereferencing the address.


For the intrinsic types, (1) is faster.

For a huge type, an object of which is perhaps a kilobyte, (2) would be
faster.


I'm sure the others can give you a more detailed reply.
