Module Name:
SrvStInf.c
Abstract:
This module only contains RxNetServerSetInfo.
Author:
John Rogers (JohnRo) 05-Jun-1991
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.) Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
05-Jun-1991 JohnRo Created. 07-Jun-1991 JohnRo PC-LINT found a bug calling RapTotalSize(). 14-Jun-1991 JohnRo Call RxRemoteApi (to get old info) instead of RxNetServerGetInfo; this will allow incomplete info level conversions to work. 10-Jul-1991 JohnRo Added more parameters to RxpSetField. 17-Jul-1991 JohnRo Extracted RxpDebug.h from Rxp.h. 21-Nov-1991 JohnRo Removed NT dependencies to reduce recompiles. 04-Dec-1991 JohnRo Change RxNetServerSetInfo() to new-style interface. 07-Feb-1992 JohnRo Use NetApiBufferAllocate() instead of private version.

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