-the catalog database keeps track of three mappings:
- CNID -> dev/ino and did/name
- dev/ino -> CNID
- did/name -> CNID
-
-dev/ino is used to keep track of magically moved files. did/name is
-for quick lookups of CNIDs.
-
-NOTE: the database will append a nul byte to the end of name. in
-addition, name should be given as it appears on disk. this allows the
-creation of cnid updating/cleaning programs that don't have to deal
-with knowing what the particular codepage is.
-
-here's the ritual:
- 1) open a volume. call cnid_open.
- 2) every time you need a CNID, call cnid_add(). it will
- automatically look for an existing cnid and add a new one
- if one isn't already there. you can pass a hint if you
- want. the only use this has right now is to enable
- consistency between AFP and HFS. in the future, it would
- allow people to write conversion utilities that
- pre-instantiate a database without needing to re-assign
- CNIDs.
- 3) if you want to just look for a CNID without automatically
- adding one in, you have two choices:
- a) cnid_resolve takes a CNID, returns name, and
- over-writes the CNID given with the parent DID. this
- is good for FPResolveID.
- b) cnid_lookup returns a CNID corresponding to the
- dev/ino,did/name keys. it will auto-update the catalog
- database if there's a discrepancy.
- NOTE: cnid_add calls this before adding a new CNID.
- 4) when you delete a file or directory, you need to call
- cnid_delete with the CNID for that file/directory.
- 5) call cnid_close when closing the volume.
