<1> Fixed a conflict with ioctl usage. There were two different
|
|
functions using code #25. Made file formatting consistent.
|
|
Added two new ioctl codes: door closing and audio pitch playback.
|
|
Added a STEREO union called STEREO.
|
|

|
|
|
|
<2> Added a new ioctl that allows you to find out what capabilities
|
|
a drive has and what commands it will accept. This allows a
|
|
user application to only offer controls (buttons, sliders, etc)
|
|
for functions that drive can actually do. Things it can't do
|
|
can disappear or be greyed-out (like some other system).
|
|
If the driver doesn't respond to this call, well, handle it the
|
|
way you used to do it.
