* As of Linux 2.1.x, all Linux CD-ROM application programs will use this
* (and only this) include file. It is my hope to provide Linux with
* a uniform interface between software accessing CD-ROMs and the various
* device drivers that actually talk to the drives. There may still be
* 23 different kinds of strange CD-ROM drives, but at least there will
* now be one, and only one, Linux CD-ROM interface.
*
* Additionally, as of Linux 2.1.x, all Linux application programs
* should use the O_NONBLOCK option when opening a CD-ROM device
* for subsequent ioctl commands. This allows for neat system errors
* like "No medium found" or "Wrong medium type" upon attempting to
* mount or play an empty slot, mount an audio disc, or play a data disc.
* Generally, changing an application program to support O_NONBLOCK
* is as easy as the following:
* - drive = open("/dev/cdrom", O_RDONLY);
* + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
* It is worth the small change.
*
* Patches for many common CD programs (provided by David A. van Leeuwen)
* can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
