Question

I’m trying to extract the class type from a pointer passed into a macro. Here’s what i have so far

template <class CLASS> class getter
{
public:
    typedef CLASS type;
};
template <class CLASS> getter<CLASS> func(const CLASS* const)
{
    return getter<CLASS>();
}
...
#define GETTYPE(PTR) func(p)::type
...
MyClass *p = new MyClass;
...
GETTYPE(p) myClass;

Is this even possible? Am I barking up the wrong tree?

You can use decltype in C++11.
