OBJECT_ATTRIBUTES The OBJECT_ATTRIBUTES structure specifies attributes that can be applied to objects or object handles by routines that create objects and/or return handles.
SINGLE_LIST_ENTRY A SINGLE_LIST_ENTRY structure describes an entry in a singly linked list, or serves as the header for such a list.
