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

44 * accomplish this. Maybe someday we will get a more targeted error code,
