[cfe-dev] how to get info from Decl

[Jochen Wilhelmy]

Hi!

I have implemented HandleTopLevelDecl in an own ASTConsumer
and want to get some Info from the declarations.

I already get the function names and the names of the
parameters, but how can I get the type of the arguments out of
ParamVarDecl?

If a function is extern "C", I get a LinkageSpecDecl, but how
do I get the function inside this declaration?
