Is it OK to use void as an argument in a template-class. Example:
template <class Pointer>
class Base
{
public:
Base() { }
virtual ~Base() { }
virtual void DoIt() = 0;
static void func(Pointer* client_data) { ((Base*)client_data)->DoIt(); }
};
Base<void> test; // legal?
This is to be used in a general template class for callback functionality.
Another question while I am at it:
I believe that a static member function had no guarantee that the linkage
was the same as for C-functions. Is that still so, according to the upcoming
standard?
