One other thing: libparted has a nice (IMHO) error handling system.

It's VERY simple :)  (have a look in include/parted/exception.h)

I have found the first particularly useful: it is BAD to stop a resize,
just because you found 1 bad sector, or whatever.

In the ntfs case when properly implemented finding a bad sector will just add the cluster in which it lies to $BadClus and remap it on disk and write it out again, no need to give errors / exceptions. But I doubt you would ever see a bad sector on a modern disk... More likely the disk will die altogether before that.

So, what do you think?  Options:
* cut&paste
* create a similar system, and make libparted wrap it, to integrate
with libparted's system

Thanks, but we would like to keep libntfs as C for now.

Why can't libparted recognize error return values from libntfs and do whatever it likes with them? You can then use your exceptions once the error code path has left libntfs and has come back to libparted... You can then always retry the libntfs call if you were so inclined.
