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/ 38 * 39 *******************************************************/ 40 41/* When a driver supports a certain function, but the cdrom drive we are 42 * using doesn't, we will return the error EDRIVE_CANT_DO_THIS.
