Copyright (c) 1992-1993 Microsoft Corporation
Module Name:
ImpBuild.c
Abstract:
This file contains ImportDirBuildApiRecord. This is used by
NetrReplImportDirGetInfo and NetrReplImportDirEnum.
Author:
John Rogers (JohnRo) 08-Jan-1992
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
Requires ANSI C extensions: slash-slash comments, long external names.
Notes:
This code assumes that the import dir info levels are subsets of each other.
Revision History:
08-Jan-1992 JohnRo
Created.
24-Jan-1992 JohnRo
Changed to use LPTSTR etc.
27-Jan-1992 JohnRo
Changed interface to allow use when service is not running.
21-Feb-1992 JohnRo
Fixed bug checking state parameter.
UncMaster parm is optional.
Added check of UncMaster validity.
Undid redundant checks of Buffer (3 of them!)
21-Feb-1992 JohnRo
Changed ImportDirBuildApiRecord() so master name is not a UNC name.
22-Feb-1992 JohnRo
Made changes suggested by PC-LINT.
26-Feb-1992 JohnRo
Check lock fields for validity.
API records now contain timestamps instead of elapsed times.
Added assertion of valid record at end.
25-Mar-1992 JohnRo
Avoid obsolete state values.
27-Mar-1992 JohnRo
Allow MasterName to point to a null char.
28-Jul-1992 JohnRo
RAID 2274: repl svc should impersonate caller.
Added debug output of structure after we build it.
30-Apr-1993 JohnRo
Use NetpKdPrint() where possible.
