I'm trying to make my Think C 4.0 code fully upward compatible with C++ so
I can run things on some of the minicomputers around here.  I've got
one problem which could mean some serious headaches.
 
In my Think C version of persistency (remember that
there are no automated constructor/destuctor functions available)
I was making use of the fact that in Think C a class name is itself a
void pointer.  For example, if I create the class Persistent, then I can
define a member function returning a void pointer like this:
 
    void  *Persistent::get_class(void)
    {
        return Persistent;
    }
 
Neat, eh?  Now, in C++ this gives a syntax error.  My question is:  Is
there any way of passing class names like this in C++???????????
 
Thanks in advance!
