||
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/ |
