I'm not sure if we actually do the same thing. I need to know if the
function returns something that is qualified and use

FunctionDecl* fD;
...
fD->getType().isConstQualified()
fD->getType().isVolatileQualified()

But you wrote something about getting NULL which can't happen here. That
is why I was wondering how you try to do it. You could also have a look
at the old thread on this list [1]. Maybe you can use some of the advice
I got.
