/*++

Copyright (c) 1991-1998  Microsoft Corporation

Module Name:

    nspapi.h

Abstract:

    Name Space Provider API prototypes and manifests. See the
    "Windows NT NameSpace Provider Specification" document for
    details.


Environment:

    User Mode -Win32

Notes:

    You must include "basetyps.h" first. Some types should
    use definitions from base files rather than redefine here.
    Unfortunately, so such base file exists.
