Copyright (c) 1991 Microsoft Corporation
Module Name:
fsnode.hxx
Abstract:
This module contains the declaration for the FSNODE class. FSNODE stands
for File System NODE and is an abstract class for all user visible
objects that exist in a file system (e.g. files, directories).
Author:
David J. Gilman (davegi) 09-Jan-1991
Environment:
ULIB, User Mode
Notes:
Do not confuse this class or it's derived classes with the IFS class
sub-hierarchy. FSNODE related classes are user visible classes. They
are not intended to be used for low level file system tasks such as
format or chkdsk. FSNODE classes are as file system independent as the
underlying system allows.
