C++ void template?

Question

i just learn c++ template. and i do some experiment with it. and i finally i facing a problem.

take a look this code:
#include <iostream>
//using namespace std; //bad idea
template <class A, class B>
class kevin
{
public:
void fung1(A a, B b);
};
template <class A, class B>
void kevin<void>::fung1(A a, B b);//error, how to do that?
//what i know, <void> is data type that will returned
int main(){}

little confusing
