What do you mean by fail? Throwing exception? Access violation? C++ has try/catch for handling non-fatal program-driven exceptions. Or were you actually looking for something else?

I was under the impression that the only things you should put in constructors/destructors were things that would not fail (or else you deal with the exceptions inside the constructor/destructor).

No, I'm saying that you shouldn't have code in your destructor that can fail.

If you can't achieve that then you handle then use try/catch in your destructor around the part that may fail.
