Yes, good advice, especially the object part. I was just looking to
see how I did this, and it is always with objects.
But I was thinking that your main program could have a garbage
container, and that you could pass a reference to that to
your function, too. The function could put all the "helper"
objects into the container before it returned. That way you
have one container to destroy at the end and you get everything.
Cheers,
