Sorry, this code used one of my proposed changes to AutoAlloc that was never added officially. To use AutoAlloc in this way you'll have to add this constructor:

    
    
    template <class TYPE> class AutoAlloc  
    {  
        TYPE *ptr;  
      
      public:  
     **     AutoAlloc(TYPE* initptr) { ptr = initptr; }  
    **  
        AutoAlloc()           { ptr = TYPE::Alloc(); }  
        AutoAlloc(LONG id)    { ptr = TYPE::Alloc(id); }  
        AutoAlloc(LONG p1, LONG p2)   { ptr = TYPE::Alloc(p1,p2); }  
        ~AutoAlloc()          { TYPE::Free(ptr); ptr = NULL; }  
        operator TYPE* ()     { return ptr; }  
        operator TYPE& ()     { return *ptr; }  
        TYPE *operator -> ()  { return ptr; }  
        TYPE *const *operator & ()  { return &ptr; }  
        TYPE *Release() { TYPE *tmp=ptr; ptr=NULL; return tmp; }  
    };
