|
|
|
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.
|
|
|
|
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).
