Module Name:

    priolist.cxx

Abstract:

    Contains prioritized, serialized list class implementation

    Contents:
        CPriorityList::Insert
        CPriorityList::Remove

Author:

    Richard L Firth (rfirth) 03-May-1997

Notes:

    Properly, the CPriorityList class should extend a CSerializedList class, but
    we don't currently have one, just a serialized list type (common\serialst.cxx).

    WARNING: Code in this module makes assumptions about the contents of a
    SERIALIZED_LIST
