  virtual CRuntimeClass* GetRuntimeClass() const;
 
  Remarks
 
  There is one CRuntimeClass structure for each CObject-derived class. The
  structure members are as follows:
 
  const char* m_pszClassName        A null-terminated string containing
                                    the ASCII class name.
 
  int m_nObjectSize                 The actual size of the object. If the
                                    object has data members that point to
                                    allocated memory, the size of that
                                    memory is not included.
 
  WORD m_wSchema                    The schema number (-1 for
                                    nonserializable classes). See the
                                    IMPLEMENT_SERIAL macro for a
                                    description of schema number.
 
  void (*m_pfnConstruct)(void* p)   A pointer to the default constructor
                                    of your class (valid only if the class
                                    is serializable).
 
  CRuntimeClass* m_pBaseClass       A pointer to the CRuntimeClass
                                    structure that corresponds to the base
                                    class.
 
  This function requires use of the IMPLEMENT_DYNAMIC or IMPLEMENT_SERIAL
  macros in the class implementation. You will get incorrect results
  otherwise.
 
  Return Value
 
  A pointer to the CRuntimeClass structure corresponding to this object's
  class; never NULL.
 
  Example
 
  CAge a(21);
  CRuntimeClass* prt = a.GetRuntimeClass();
  ASSERT( strcmp( prt->m_pszClassName, "CAge" )  == 0 );
