I have a bit of a problem here. I have made a function that has a void pointer as an argument, so this could point to any adress in memory and any data type too, but I have to make sure the pointer points to a valid instance of any class that is derived from an abstract base class. Is this even possible?

Then you shouldn't be using a void pointer. Use a pointer to the base class.
I'd do that, but I want to keep the function as open as possible. Well, if there's no other solution that's what I'll do.
Thanks, and congrats on your 1000th post. :)
You can use templates to accomplish the same thing.
Hmm... I don't quite know how templates work, but I'll look it up. (I recall there's a tutorial on that in the tutorials section of this board's main site)
Anyway, right now I'm going to sleep. g'night!
As SilentStrike has stated use templates; then if you want to ensure that something is done when you use the function with a specific type, create a specialisation.
