|
|
Environment:
|
||
|
|
|
||
|
|
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
|
||
|
|
Requires ANSI C extensions: slash-slash comments, long external names.

19-Aug-1991 JohnRo
|
||
|
|
Implement downlevel NetWksta APIs.
|
||
|
|
21-Nov-1991 JohnRo
|
||
|
|
Removed NT dependencies to reduce recompiles.
|
||
|
|
07-Feb-1992 JohnRo
|
||
|
|
Use NetApiBufferAllocate() instead of private version.
|
||
|
|
02-Apr-1992 JohnRo
|
||
|
|
Fixed bug in setinfo of level 402 (was causing GP fault in strlen).
|
||
|
|
03-Nov-1992 JohnRo
|
||
|
|
RAID 10418: NetWkstaGetInfo level 302: wrong error code.
|
||
|
|
Use PREFIX_ equates.

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