how about using "hdiutil info -plist"? That'll give you
information about the currently mounted disk images, in a convenient
plist format.
This does indeed seem like a better way to solve this issue!
Best,

Hello Brad,
you could use the hdiutil tool to try to unmount the volume your
running application resides on. The unmount process itself should
fail, though, but the error differs for different situations.
E.g. failing to umount a disk image your app is running from contains
the error code "49153".
Failing to umount a network share will result in "no such file or
folder".
hdiutil detach /Volumes/TheVolumeYourAppResidesOn/
The exact error message might differ between system versions,
especially as these error messages posted by hdiutil are localized
(unfortunately). So you will have to experiment a bit and parse
hdiutil's output.
Also, the hdiutil man page (<x-man-page://hdiutil>) states that using
the "/Volumes/yourvolumename/" path to unmount a disk image does work
for Mac OS X 10.4 systems only – the Mac OS X 10.3 version of hdiutil
expects the device path (e.g. "/dev/disk1s2").
Run "hdiutil attach /path/to/your/diskimage" to see your mounted disk
image's device path. I do not know the tool(s) used to get the device
path for a certain mounted volume...
