/*******************************************************
 * As of Linux 2.1.x, all Linux CD-ROM application programs will use this 
 * (and only this) include file.  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.  We will 
 * borrow the "Operation not supported" error from the network folks to 
 * accomplish this.  Maybe someday we will get a more targeted error code, 
 * but this will do for now... */
