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