how to implement is_pointer?

Question

I want to implement is_pointer. I want something like this:

template 
bool is_pointer( T t )
{
   // implementation
} // return true or fa

From Dr. Dobbs.

template  
struct is_pointer 
{ static const bool value = false; };

template  
struct is_pointer 
{ static const bool value = true; };

You can't do exactly what you want to do. You'll have to use this like:

is_pointer::value

It's not possible to determine this at run time.
