Module Name:

    iterator.cxx

Abstract:

    This contains the definitions for the non-inline member functions
    for the abstract ITERATOR class. The only interesting aspect of this
    implementation is that the destructor decrements the iterator count in
    it's associated CONTAINER. This count, increment by the CONTAINER when
    the ITERATOR is constructed, allows the associated CONTAINER to watch
    for outstanding ITERATORs when it is destroyed - a situation which is
    dangerous and surely a bug.

Environment:

    ULIB, User Mode
