Well, I see no reason why your code should be faster to write than portable
code. Besides the fact that portable code (using e.g. libscg) may be written
in exactly the same time, it will take advantage of the SCSI error decoder and
print readable error messages.

I don't understand you - sorry.
If you are talking about the IMMED bit, well I was experimenting with it
4 years before you send your mail......
With get confiruration, it seems that you don't know that this is a MMC-3 only
command. I am not sure whether a single CD writer supports it (besides the Sony
CDU-200 which is DDCD).
OK, DVD writers and something called DVD+RW although not DVD from current
standards support it. Writing portable software that supports many drives is
different from writing a demonstrator for a single drive type.

Nowyou got it: only MMC-3 drives support get configuration. This is a small
minority of drives.
