WksGtOld.c
Abstract:
This file contains RxpWkstaGetOldInfo().
Author:
John Rogers (JohnRo) 15-Aug-1991
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
15-Aug-1991 JohnRo
Implement downlevel NetWksta APIs.
11-Nov-1991 JohnRo
Moved some code from RxNetWkstaGetInfo to RxpWkstaGetOldInfo, so it
can be shared by RxNetWkstaUserEnum.

RAID 7243: Avoid 64KB requests (Winball servers only HAVE 64KB!)
Use PREFIX_ equates.

Routine Description:
RxpWkstaGetOldInfo does a WkstaGetInfo to a downlevel server for an
old info level.
Arguments:
(Same as NetWkstaGetInfo, except UncServerName must not be null, and
must not refer to the local computer.)
Return Value:
(Same as NetWkstaGetInfo.)
