[cfe-dev] how to determine a parameter has a type declarator inclang

[kevinlynx]

Thanks, it worked on 1 parameter function, but does not work on more than one parameters function, say,

    void func(int a, b)

`hasWrittenPrototype` still return true, and `b` will also get a default `int` type.

You can ask whether the function has a written prototype.
