Access Violation Exception C++
It would be nice to be able to automatically unregister a user-defined callback if it is found to cause any exception including access violations. For details, see here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms680657%28v=vs.85%29.aspx In effect, you can register to get a callback when an exception happens. It can't be. For code written for previous versions of the .NET Framework that you want to recompile and run without modification on the .NET Framework 4, you can add the
Thanks for the hint. –Ralph Tandetzky Jan 30 '13 at 19:40 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign Do you think those platforms that do define 'access violation' mean the same thing by that term? Any specific example code to show how to handle the access violation will be extremely helpful!

Then, I do TerminateProcess() to self-kill. –Петър Петров Sep 11 '13 at 15:34 4 It is a bad idea to catch an exception and silently ignore it. Things like access violations or division by zero errors are more like "machine" exceptions, rather than language-level things that you can catch. Still upvoting for an interesting solution. See Project Properties -> C/C++ -> Code Generation -> Modify the Enable C++ Exceptions to "Yes With SEH Exceptions".

The right approach here is to have a known "jump" exception, of course. Handleprocesscorruptedstateexceptions An access violation in unmanaged code that bubbles up to managed code is always wrapped in an AccessViolationException exception.In either case, you can identify and correct the cause of the AccessViolationException How do I create armor for a physically weak species?

But it seems implausible: SEH can arise from fetch or store which are often resequenced - so this would restrict the available optimisations. The code in the question is undefined, which means that anything can happen, and be different each time. –KeithB Jan 19 '09 at 14:27 6 Catching Access Violation is not
