Is there a favored idiom for mimicing Java's try/finally in C++?

Question

Been doing Java for number of years so haven\'t been tracking C++. Has finally clause been added to C++ exception handling in the language definition?<

Answer 1

I've done plenty of class design and template wrapper design in C++ over those 15 years and done it all the C++ way in terms of destructors cleaning up. Every project, though, also invariably involved the use of C libraries that provided resources with the open it, use it, close it usage model. A try/finally would mean such a resource can just be consumed where it needs to be - in a completely robust manner - and be done with it. The least tedium approach to programming that situation. Could deal with all the other state going on during the logic of that cleanup without having to be scoped away in some wrapper destructor.

I did most of my C++ coding on Windows so could always resort to using Microsoft's __try/__finally for such situations. (Their structured exception handling has some powerful abilities for interacting with exceptions.) Alas, doesn't look like C language has ever ratified any portable exception handling constructs.

That wasn't ideal solution, though, because it was not straightforward to blend C and C++ code in a try block where either style of exception might get thrown. A finally block added to C++ would have been helpful for those situations and would enable portability.
