[cfe-dev] a question regarding clang::Type::isFunctionPointerType()

[Erik Pilkington via cfe-dev]

Well, only the first is a pointer to a function, the others are pointers to pointers to functions. I guess you probably would want to drill down through the type, using PointerType::getPointeeType() until you reach the function pointer, then check to see if that is a pointer to a function.
