							|  |  |  |  * 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/
