Re: [Plug] Re: Simple Question...

I was searching through the source code earlier (prompted by your
post), and I found a few references. I was not, however, able
to track them to something definate. I started (probably as you
did) looking for serial number, sn, etc. I did find a reference to
a 13 digit ASCII string called medium_catalog_number. This is
at /usr/src/linux/include/linux/cdrom.h:152. Now, I don't
know if this is in fact what you're looking for or not, but I
went further.
I've sited something that says its called the Medium Catalog Number,
is that what you're looking for?
From: /usr/usr/linux/drivers/cdrom/cm206.c:1044
369 /* The following function is implemented, although very few audio
370 * discs give Universal Product Code information, which should just be
371 * the Medium Catalog Number on the box. Note, that the way the code
372 * is written on the CD is /not/ uniform across all discs!
373 */
374 case CDROM_GET_MCN: {
375 struct cdrom_mcn mcn;
376 if (!(cdo->capability & CDC_MCN))
377 return -EINVAL;
378 if (!cdo->get_mcn(dev, &mcn)) {
379 PUTARG(struct cdrom_mcn, mcn);
380 return 0;
381 }
382 return -EINVAL;
This infor should be available via
ioctl(fd,CDROM_GET_MCN,snptr);
