Module Name:
ExpSet.c
Abstract:
This file contains NetrReplExportDirSetInfo.
Author:
John Rogers (JohnRo) 08-Jan-1992
Environment:
Runs under Windows NT.
Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
08-Jan-1992 JohnRo
Created.
09-Jan-1992 JohnRo
PC-LINT found a bug.
20-Jan-1992 JohnRo
Changed prototype to match MIDL requirements.
24-Jan-1992 JohnRo
Changed to use LPTSTR etc.
15-Mar-1992 JohnRo
Update registry with new values.
Use improved setinfo support from ExpDir.h.
22-Jul-1992 JohnRo
RAID 2252: repl should prevent export on Windows/NT.
Added debug output.
26-Aug-1992 JohnRo
RAID 3602: NetReplExportDirSetInfo fails regardless of svc status.
29-Sep-1992 JohnRo
RAID 7962: Repl APIs in wrong role kill svc.
Fix remote repl admin.
30-Dec-1992 JohnRo
RAID 5340: NetReplExportDirSetInfo is confused (when role=import).
05-Apr-1993 JohnRo
Use NetpKdPrint() where possible.
Made some changes suggested by PC-LINT 5.0
