Only if the new API compliance is enabled by macro Cdrskin_new_api_tesT .
There is a flaw to be solved in libburn until new API compliance is in all
aspects as good as the old handcrafted attempt to be sysadmin friendly.
In many aspects it is already superior, note well.
As soon as the flaw http://libburn.pykix.org/ticket/10 is removed,
cdrskin will switch to its new way of API best practice compliance.

Not yet by default. In many aspects this is already superior, note well :
This is because Cdrskin_grab_drive() enforces a restart of the library
with the desired drive's persistent address. This restart then really uses
the strongly urged function burn_drive_scan_and_grab().
Burns without dev= resp. with dev=number are harmless on multi-drive systems.
This is because Cdrskin_grab_drive() either drops the unwanted drives or
it enforces a restart of the library with the desired drive's persistent
address. This restart then really uses the strongly urged function
burn_drive_scan_and_grab().
Thus, cdrskin complies with the new spirit of API by closing down libburn
as soon as the persistent drive address is known and the drive is to be
used with a long running operation. To my knowlege all long running
operations in cdrskin need a grabbed drive.
or by dropping unused drives as soon as the persistent drive address is

This spaghetti approach seems necessary to keep small the impact of new API
urge on cdrskin's stability. cdrskin suffers from having donated the body
