"Can C++ functions marked as Extern “C” throw?"

Yes, in the sense that neither the language nor the compiler will prevent you from doing so.

No, in the sense that if you throw, it would be an undefined behaviour, as the C++ exception crosses language boundaries.

In practice: do not do it. Catch the exception and translate it into an error code, or a means the other language can understand.

So the bottomline is: do NOT throw exception from functions marked as extern "C".
