/******************************************************* |
|
* 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/ |
