It is my hope to provide Linux with * a uniform interface between software accessing CD-ROMs and the various * device drivers that actually talk to the drives. There may still be * 23 different kinds of strange CD-ROM drives, but at least there will * now be one, and only one, Linux CD-ROM interface. * * Additionally, as of Linux 2.1.x, all Linux application programs * should use the O_NONBLOCK option when opening a CD-ROM device * for subsequent ioctl commands. This allows for neat system errors * like "No medium found" or "Wrong medium type" upon attempting to * mount or play an empty slot, mount an audio disc, or play a data disc. * Generally, changing an application program to support O_NONBLOCK * is as easy as the following: * - drive = open("/dev/cdrom", O_RDONLY); * + drive = open("/dev/cdrom", O_RDONLY | O_NONBLOCK); * It is worth the small change. * * Patches for many common CD programs (provided by David A. van Leeuwen) * can be found at: ftp://ftp.gwdg.de/pub/linux/cdrom/drivers/cm206/ * *******************************************************/ /* When a driver supports a certain function, but the cdrom drive we are * using doesn't, we will return the error EDRIVE_CANT_DO_THIS.
