Copyright (c) 1990 - 1995 Microsoft Corporation
Module Name:
net.c
Abstract:
This module provides all the network stuuf for localspl
Author:
Dave Snipp (DaveSn) 15-Mar-1991
Notes:
We just need to get the winspool printer name associated with a given
queue name. The SHARE_INFO_2 structure has a shi2_path field that would
be nice to use, but NetShareGetInfo level 2 is privileged. So, by
DaveSn's arm twisting and agreement with windows/spooler/localspl/net.c,
we're going to use the shi1_remark field for this. This allows us to
do NetShareGetInfo level 1, which is not privileged.
BUGBUG: After NT beta, find a better way to do this! Perhaps a new info
level? --JR (JohnRo)
This has been fixed by allowing OpenPrinter to succeed on share names.
If there is no comment, we put the printer name in as the remark
(for graceful upgrades from pre-PPC).
