I'd like to learn how to mount a file as a r/w volume, much like what DisckCopy does with its ".dmg" files.

I have implemented my custom read, write and seek function calls, but I don't know where to put them.

I've already created an app (ZeeProxy) capable of reading from and writing to my (opensource) "disk image" format, called RAZip (*), but I'd like to make it available system-wide.

Shuld I write a kext, or user-space is good enough for the task?
Oh, where can I find the headers for DiskImages.framework? (They don't show up in PB's files tab). And where can I get "hdid" and "hdiutil" source code ?

Thanks a lot for any help!

(*) RAZip is in fact a bitstream format used to store losslessly compressed data, providing excellent random-access read rates, and good random write rates in the near future too. I created RAZip because random read rates from a GZIP-compressed data stream are disappointingly low. Besides, RAZip can store a lot of useful meta-data.For more details, see :

Someone replied to my post, but it got lost after the attack last night, and I haven't had the chance to read it. Could the poster repost, please?

Thanks.

P.S.: I'd like to be able to mount the image files under MacOS X and under vanilla Darwin as well, so I'd like to rely on as little non-open-source code as possible.

It was me, but I've also replied to your e-mail to one of the developer lists I'm subscribed to. I"m not going to re-type it for the third time.
