| 18 | * As of Linux 2.1.x, all Linux CD-ROM application programs will use this |
| 19 | * (and only this) include file. It is my hope to provide Linux with |
| 20 | * a uniform interface between software accessing CD-ROMs and the various |
| 21 | * device drivers that actually talk to the drives. 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/ |
