To create an iterator for a doubly linked list of CMyClass elements, +defined as:

+class CMyClass : public CBase + { + ... + TDblQueLink iDlink; + ... + }; +

first construct a header:

+TDblQue<CMyClass> queHeader(_FOFF(CMyClass,iDlink)); +

and then construct the iterator. The iterator requires the header at construction +time but the list can be empty:

+TDblQueIter<CMyClass> queIter(queHeader); +

The TDblQueIter class takes a class template parameter +that defines the type of object which is to form an element of the list.
