Re: pathnames in Tiger not showing volume name

So apparently I can't read.  Tiger/Leopard they're both cats...

Indeed, I ran my test under 10.5. Under 10.4 I see the behaviour that
you are seeing.

Under 10.4, if I mount two shared directories (DEV and FOO) from the
same machine (say timmy.company.com) then I see "timmy.company.com"
and "timmy.company.com-1" in the /Volumes folder

I get better info from a "df" command in the Terminal.

Now, if I get the DumpVolumeInfo sample from developer.apple.com and I do this:

./DumpVolume -c /Volumes/timmy.company.com

it reports the volume name as "DEV".

So, you need to be calling FSGetVolumeInfo().
[you can create a FSVolumeRefNum via FSGetCatalogInfo()].

Take a look at the DumpVolumeInfo sample:  PrintFSGetVolumeInfo(...)

There may be a lower level Cocoa way of doing this but there you go...

Cheers,
-H.
