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/

45 * accomplish this. Maybe someday we will get a more targeted error code,
46 * but this will do for now... */
