The relevant bits of which are:
[really interesting code]
And the tiebreaker question is ;) :
Is there a more direct way to open the CD tray, by using the
IOKit by
instance ? It's a bit tricky to simulate a keystroke just to open
the
CD tray. If I recall well, the command line tool hdiutil may be used
to open it.
/System/Library/Frameworks/DiscRecording.framework/Versions/A/
Frameworks/DiscRecordingEngine.framework/Versions/A/Headers/
DRDevice.h
has an method: - (BOOL) openTray; // Commands the device to open
it's tray.
This might be even easier than using the IOKit.
Kind regards,
Gerriet.
