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

43 | * accomplish this. Maybe someday we will get a more targeted error code, | |
