I'm writing a cocoa app that needs to be able to detect a file's type and creator codes, but I've hit a wall. I've found sources that say that this is currently only available with Carbon; yet, there was a Cocoa app called Cocoa Type Changer that came with source code that did exactly what I need. It was located at http://www.merespass.net/software.shtml but that server has disappeared.

Does anyone have the code from this app?
Or does anyone here know how to access and modify this info in Cocoa?

There seems to be a DNS problem with that hostname; but if you go to the registered primary DNS server for that domain you'll find its IP is 146.115.208.16, and you can use that to connect.

Source code doesn't seem to be available though.

To get the file type, you can use the NSHFSTypeOfFile() function in Foundation/NSHFSFileTypes.h. I'm not sure about creator though. The app in question does link against Carbon, and seems to reference the FSGetCatalogInfo(), FSPathMakeRef(), FSpGetFInfo(), FSpSetFInfo(), LSCopyItemInfoForURL(), LSCopyKindStringForURL(), LSGetApplicationForInfo(), and LSInit() functions. Not sure which of those (if any) are used in getting the creator though.

Those HFS-calls won't work on NFS/UFS/MSDOS/WEBDAV-devices (Carbon emulates those features on single-forked disks).

But implementing Carbon calls into Cocoa isn't that complicated. Just add Carbon.framework to your framework, #include <Carbon/Carbon.h> and use the functions you want.

And for less bloat just add CoreServices (which includes CarbonCore and therefore Files.h and everything you should need).
