16/*******************************************************
17 * As of Linux 2.1.x, all Linux CD-ROM application programs will use this
18 * (and only this) include file. It is my hope to provide Linux with
19 * a uniform interface between software accessing CD-ROMs and the various
20 * device drivers that actually talk to the drives. There may still be
21 * 23 different kinds of strange CD-ROM drives, but at least there will
22 * now be one, and only one, Linux CD-ROM interface.
23 *
24 * Additionally, as of Linux 2.1.x, all Linux application programs
25 * should use the O_NONBLOCK option when opening a CD-ROM device
26 * for subsequent ioctl commands. This allows for neat system errors
27 * like "No medium found" or "Wrong medium type" upon attempting to
28 * mount or play an empty slot, mount an audio disc, or play a data disc.
29 * Generally, changing an application program to support O_NONBLOCK
30 * is as easy as the following:
31 * - drive = open("/dev/cdrom", O_RDONLY);
32 * + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK);
33 * It is worth the small change.
34 *
35 * Patches for many common CD programs (provided by David A. van Leeuwen)
36 * can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/

40/* When a driver supports a certain function, but the cdrom drive we are
41 * using doesn't, we will return the error EDRIVE_CANT_DO_THIS. We will
42 * borrow the "Operation not supported" error from the network folks to
43 * accomplish this. Maybe someday we will get a more targeted error code,
44 * but this will do for now... */
