C++ template and Function Pointer issue

[enliten]

Hello,

I am trying to pass a double templated C++ function as function pointer to a C system. The underling system takes function pointer of the form

void (*)(void **, void *)

When I try to pass some member function that is templated on itself and the enclosing call. I dont know how to specify template parameters for each type of template parameters.

To demonstrate this, I write a simple c++ template class

template <typename T1, typename T2>
class Abc
{
   ....
   template<typename T3>
   void abc(void **buf, void *arg)
   {
      ....
   }

   ...
   void MakeCall()
   { 
      ...  st;
      st.cpu_pointer = abc<float>; // gives error on this line, specifying only for function template??
   }
}

I have a feeling it's more because abc is a member function than that it is a template function.

You won't be able to pass a member function (even non-templated) as a function pointer through that signature.

If abc() were a static function, then the syntax would be

Abc<T1,T2>::abc<T3>

substituting your real types for T1, T2, T3.
