Hi all,

I have a class with protected and/or private members that need to be accessed by 
a close relative but template class. Normally one would make the second class 
friend of the first, but when this second class is a template, how can I 
accomplish it then?

//#
//# class A
//#
class A
{
public:

friend class B;		//* This wont work, because class B is template

private:
	void privateFunction();
};
//#
//# template class B
//#
template <class XType>
class B
{
public:
	void myFunction( A *ptrA )
	{ ptrA->privateFunction(); }
};
//#
//#

Any ideas would be greatly appreciated.

Wiljo.
