[cfe-dev] [libClang] Get name of method parameter or variable type

[Alexander Droste via cfe-dev]

Good point. I missed that you're using the C interface but it seems like
similar functionality is available there:
clang_getPointeeType
https://github.com/llvm-mirror/clang/blob/master/include/clang-c/Index.h#L3437

clang_getElementType
https://github.com/llvm-mirror/clang/blob/master/include/clang-c/Index.h#L3513

Though, I couldn't find functionality to remove the qualifiers.
