Nevermind. I was looking at the wrong API.
As for using DARegisterDiskDescriptionChangedCallback() for
mounts, I think that's incorrect.
DARegisterDiskDescriptionChangedCallback() is meant to track disk
that are already mounted and changing either their name or path. I
think your really want DARegisterDiskAppearedCallback().
Hmm, won't that be called when the disk appears in IOKit and not
when it's mounted? I don't really care about the former. Or will it
be called both for attach and mount? If that's the case, then I
could use the volumePath key in the Disk dictionary to determine if
it's being mounted.
Also, if ChangedCallback() is not supposed to be used, then the
documentation should be clarified:
/*!
* @constant kDADiskDescriptionWatchVolumePath
* Predefined CFArray object containing a set of disk description
keys appropriate for
* watching volume mount changes using
DARegisterDiskDescriptionChangedCallback().
*/
extern CFArrayRef kDADiskDescriptionWatchVolumePath;
I take "watching volume mount changes", to mean changing from
mounted - -> unmounted OR vise-versa. "watching volume un-mounts"
would be a better term if that is all ChangedCallback does.
Thanks for the quick response!

The third argument is supposed to be a CFArrayRef of keys to
watch, not a CFDictionaryRef. You might want to try fixing that,
then retest...
