But what is the API call (C, C++ or Obj C) for this ?

Thank you for you reply.

According to both Finder.h and SetFile --help, you can't set the bundle bit on a
folder. If you'd like to try anyway, here's some C++:

FSCatalogInfo info;
ThrowIfOSError(::FSGetCatalogInfo(&folder, kFSCatInfoFinderInfo, &info, 0, 0,
0));
FileInfo& finderInfo = *reinterpret_cast<FileInfo*>(&info.finderInfo);
finderInfo.finderFlags |= kHasBundle;
ThrowIfOSError(::FSSetCatalogInfo(& folder, kFSCatInfoFinderInfo, &info));

On my system, 'SetFile --help' doesn't say anything about that. The bit
is used to indicate 'packageness' - see
http://developer.apple.com/documentation/Carbon/Conceptual/carbon_porting_guide/
cpg_prepstruct/chapter_2_section_5.html#//apple_ref/doc/uid/TP30000991-CH202-BAB
BFHIH

"On Mac OS X, a bundle hierarchy normally appears as a single file,
unless the bundle bit is unset, in which case it appears as a folder
hierarchy."

You probably didn't read to the end:

Note: The following attributes may be used with the -a option:
A Alias file
B Bundle
C Custom icon*
D Desktop*
E Hidden extension*
I Inited*
M Shared (can run multiple times)
N No INIT resources
L Locked
S System (name locked)
T Stationery
V Invisible*
Z Busy*

Note: Items marked with an asterisk (*) are allowed with folders

But I agree with your interpretation of the bundle packaging documentation.

I think we're running into a terminology problem here:

-> In the Classic days (6.x - 9.x), there was a bundle resource ('BNDL')
that contained type <---> icon mappings. kHasBundle tells the Finder
that a file has a BNDL resource and it should scan it and add it to the
"desktop database".

-> In 9.x, Apple backported the concept of NeXT-style folder-based
applications, which NeXT called bundles, but Apple called packages. For
these packages, they introduced the package flag to the extended Finder
flags. SetFile() (mentioned by another poster) only accesses the
original Finder flags. You need to use FSSetCatalogInfo() and typecast
around a little to change the extended catalog info.

That said, I couldn't find the constant for the 'file package' flag in
the newest Carbon headers. Which isn't too surprising, as it isn't
really necessary on OS X anyway. If a folder has one of the known file
name extensions (.app, .bundle etc.) it is automatically checked whether
it's a bundle.

Is that maybe closer to what you're looking for?

I never thought the OP was discussing this issue.

SetFile utility does in fact change the relevant bit for folders,
signifying to Finder that they should be treated as packages. This is
simple to confirm.

That is probably also a good way of achieving the same effect, but I'm
not sure if that works in the OS9 Finder (which also supports the idea
of folders-as-bundles/packages through the bundle bit).

As of OS 9.1, if a folder's name has an extension, contains a Contents
folder and the Contents folder contains a PkgInfo, the Finder considers
it a package (even if the bundle bit is not set).

Add .bundle extension to the filename is just what I need.

Thank you.
