Module Name:
ConfGet.c
Abstract:
This file contains the RpcXlate code to handle the NetConfigGet API.
Author:
John Rogers (JohnRo) 24-Oct-1991
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
24-Oct-1991 JohnRo
Created.
28-Oct-1991 JohnRo
Made changes suggested by PC-LINT. (Only affects UNICODE option.)
01-Apr-1992 JohnRo
Use NetApiBufferAllocate() instead of private version.
05-Jun-1992 JohnRo
RAID 11253: NetConfigGetAll fails when remoted to downlevel.
Use PREFIX_ equates.
23-Oct-1992 JohnRo
RAID 9357: server mgr: can't add to alerts list on downlevel.
Fixed __stdcall for RpcXlate workers.

Routine Description:
RxNetConfigGet performs the same function as NetConfigGet,
except that the server name is known to refer to a downlevel server.
Arguments:
(Same as NetConfigGet, except UncServerName must not be null, and
must not refer to the local computer.)
Return Value:
(Same as NetConfigGet.)
