I'm using a RecursiveASTVisitor and implementing its VisitCallExpr() method. 
How can I get the value of struct's member? 

bool VisitCallExpr(CallExpr *expr)
    for (int i=0;i<expr->getNumArgs();i++)
            Expr* ex = expr->getArg(i);
            if (ex->getType()->isStructureType())
                //get the value of struct's member
