Re: reference to pointer used in ctor - using 'this' in ctor (repost - corrected sample code)
Anonymous wrote:

The code still doesn't compile because of numerous errors (like 'm_obj'
and 'm_objs', declarations of friends that are templates, etc. Read
the FAQ 5.8 please.
class C
{
public:
friend class A;
~C(){};
private:
C(A<C>*& parent):m_parent(parent){}
The advice is still the same:
C(A<C>* const& parent)...
A<C>* m_parent ;
};
int main( int argc, char* argv[])
{
A<B> ab ; // Ok
A<C> ac ; // Croaks here ...
};
Class A instantiated with B compiles ok, but when instantiated with
class C (that accepts a *&), I get the error message - cannot convert
parameter 1 from A const* to A* - why is that ?
Why is a reference to a ptr being passed as a const ptr ?
If 'this' is a const ptr during construction (I doubt this assertion
very much), then why is it ok to use as a non-const pointer in class
B?
