Revision History:

|
|
09-Feb-1992 JohnRo
|
|
Created this routine from code written by MadanA.
|
|
14-Feb-1992 JohnRo
|
|
ApiStatus is sometimes wrong.
|
|
05-Mar-1992 JohnRo
|
|
Changed interface to match new service controller.
|
|
06-Mar-1992 JohnRo
|
|
Avoid starting RPC server too soon.
|
|
23-Mar-1992 JohnRo
|
|
Got rid of useless master and client termination codes.
|
|
01-Apr-1992 JohnRo
|
|
Avoid assertion if import startup fails.
|
|
Up the stack size, just to be on the safe side.
|
|
19-Aug-1992 JohnRo
|
|
RAID 2115: repl svc should wait while stopping or changing role.
|
|
11-Mar-1993 JohnRo
|
|
RAID 12100: stopping repl sometimes goes into infinite loop.
|
|
Use PREFIX_ equates.
|
|
02-Apr-1993 JohnRo
|
|
Use NetpKdPrint() where possible.
|
|
24-May-1993 JohnRo
|
|
RAID 10587: repl could deadlock with changed NetpStopRpcServer(), so
|
|
just call ExitProcess() instead.
