hello everybody
since HFS+ can track up to eight fragments in a file's catalog record.
If a file has more than eight fragments, HFS+ creates additional
records, called extent records, to track the extra fragments.
i want to know how to read the eight fragments stored in file's catalog record
Are their any api's so that i can achieve this using carbon or cocoa
programming.
Thanks
santosh k
