Re: Trouble finding source of PBM error problem

Thanks Paul,

Yes this is Jaguar. I don't think I have printf's in the PBM, except for
some fprintf's that go to a log file.

I've since seen your 2 messages to this list from February that talk
specifically about the -1 error. Sorry for not searching the archives
first (or just searching my saved mail, duh).

Anyway, I found that my PM was failing with a -1 error for any I/O. Its
CreatePrinterTickets function was crashing PrintJobMgr. (I knew I needed
to debug that code). So it looks like another cause of the -1 error is a
PrintJobMgr crash.

Correcting my PM code avoids the -1 error when using say the USB PBM, but
my PBM still gets it. My PM's CreatePrinterTickets function isn't getting
called, neither is its Initialize function, and Console doesn't report
that PrintJobMgr has crashed.

Is there a way to tell what PrintJobMgr is doing? Can I invoke it
manually under the similar conditions? Is this what the "PrintJobMgr
queue-name" usage is for? I tried renaming the executables in its bundle
so PrintJobMgr_debug got used instead during a run of Print Center,
hoping to see a clue sent to Console. No dice.

Or perhaps its hasn't even gotten to PrintJobMgr yet and its not to
blame? Ah, top says differently. In my own logs, the only thing that I
can see happening at that time is a call to my PM's
CreatePrinterBrowserModuleInfo function. I'm confused, shouldn't this
have instead been called while initializing the PBM to gather the lookup
specs of the supported PMs? %:-p

Thanks for your help.

-Pierre

P.S your message was dated Jan 3, 1970. Hey, why do we get 1970 now
instead of 1904? I like 1904 better, maybe I'll file a bug :-)
