c++ - How to find declaration of a variable using Clang? -

i'm trying analyse c++ code using clang. next code, i'm able retrieve expr* x argument of f-> bar(x) ast. now, want find declaration of x in order initial value i'm not sure how this. looked expr documentation in here http://clang.llvm.org/doxygen/classclang_1_1expr.html couldn't find useful.

struct foo { int bar(int x) { homecoming x; } }; int main(){ foo *f; int x = 0, y = 0; int y = f->bar(x); homecoming 0; }

something like

dynamic_cast<const vardecl*>(dynamic_cast<const declrefexpr*>(x)->getdecl())->getinit();

c++ clang
