19   * As of Linux 2.1.x, all Linux CD-ROM application programs will use this
20   * (and only this) include file.  It is my hope to provide Linux with
21   * a uniform interface between software accessing CD-ROMs and the various
22   * device drivers that actually talk to the drives.  There may still be
23   * 23 different kinds of strange CD-ROM drives, but at least there will
24   * now be one, and only one, Linux CD-ROM interface.
25   *
26   * Additionally, as of Linux 2.1.x, all Linux application programs
27   * should use the O_NONBLOCK option when opening a CD-ROM device
28   * for subsequent ioctl commands.  This allows for neat system errors
29   * like "No medium found" or "Wrong medium type" upon attempting to
30   * mount or play an empty slot, mount an audio disc, or play a data disc.
31   * Generally, changing an application program to support O_NONBLOCK
32   * is as easy as the following:
33   *       -    drive = open("/dev/cdrom", O_RDONLY);
34   *       +    drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
35   * It is worth the small change.
36   *
37   *  Patches for many common CD programs (provided by David A. van Leeuwen)
38   *  can be found at:  ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/
