Returning the address of a member structure

Is it possible to retrieve the address of a member structure?

I tried the following code but it doesn't work:

Code:

---

class SomeClass
{
private:
struct x
{int a
} y;
public:
int struct_address(){return &y;}
}

...

cout << classinstance.struct_address() << endl;

How would you access the address of a member variable or structure or whatever?

First of all, fix your indentation.

Second, why do you even want to do this? I can't think of a good reason.

Nevermind, got it to work.

Code:

---

        ...
        int* struct_address(){return (int*) &y;}

---

FYI, I need to know how bitfield variables are configured in the memory so that I can perform a bitfield operation on them later.

that's an ugly hack. if you need to return the address of your struct, don't cast away your type info.

Code:

---


class SomeClass
{
private:
  struct x
  {
      int a
    } y;
public:
  // return type matches type being returned
  x* struct_address(){return &y;}
};

That kind of interface is very bad.
You should never allow direct access to the internal data of your class.
