[cups-devel] cupsEnumDests(): Suppress listing temporary CUPS queues or distinguish temporary queues in resulting queue list

[Till Kamppeter]

Hi,

I want to perform an operation only on the permanent queues (the ones 
manually set up) of the local CUPS daemon, not on temporary queues (the 
ones CUPS auto-creates when one accesses a driverless remote printer 
advertised by DNS-SD).

I can call cupsEnumDests() with flags so that only queues of the local 
CUPS daemon and not remote printers without local CUPS queues are 
shown), but the queues of the local CUPS daemon which I get listed then 
are both the permanent queues and temporary queues. How can I recognize 
which of these are permanent and which are temporary? Or can I call 
cupsEnumDests() in a way that I get only permanent or only temporary queues?

I uses the newest GIT snapshot of CUPS on Ubuntu 17.10 (Artful, under 
development). I have downgraded the libcups.so.2 file to right before 
commit f50db552 due to https://github.com/apple/cups/issues/5022
