Inspect contents of a basic, unencrypted UDIF DMG file

Question

If I mount the DMG file using system calls to hdiutil and my application quits unexpectedly, the DMG remains mounted but because I mount it privately with -nobrowse, it doesn't show up in Finder. Is there a way to mount it using some framework or API that will be smart enough to unmount if my application unexpectedly quits?

Basically, I'm looking for a way to be able to read from files within a DMG without having to mount it.

I think your best bet is to try to catch an exception or signal prior to exiting, and in your exception or signal handler code, unmount the DMG yourself.

You could use libdmg to directly read the dmg rather than mounting it....though it's obviously unsupported.
