How to simulate inner exception in C++

Question

Basically I want to simulate .NET Exception.InnerException in C++. I want to catch exception from bottom layer and wrap it with another exception and throw again to upper la

Answer 1

Also I am not sure whether the temporary object that is thrown from func1 will survive even after func2 throw?

No. Unless you rethrow the exception with throw;. You could implement this if you'd allow only some (limited) set of exception types.
