Well, I thought somebody from Apple would answer this, but I guess not.

It depends on a couple of values.  There is a field labeled "pathVerb".
You have to supply a value.  Depending on what this value is, the "pathDesc"
field will be one of the following:

- a pointer to a Class 1 GS/OS string.  You have to supply the pointer.
- a handle to a Class 1 GS/OS string.  You have to supply the handle.
- a handle to a Class 1 GS/OS string.  Standard File allocates it, you
have to throw it away.

The format of the GS/OS string is as follows:

- A length word indicating how much space this is taking up.
- A length word indicating how big the pathname is.
- The pathname.

I would let Standard File allocate the handle.  If you are on an AppleShare
volum, it could get quite large.  (HFS doesn't have any 64-byte partial
pathname limitations or 128 full pathname limitations).

Look, I don't mean this personally, but I see you asking lots of questions
that are answered in the Toolbox Manuals.  Do you ever read them?
The Standard File stuff is painstakingly clear (I know, I caused one of 
the sections of documentation to be written!) if you read it and you
have a knowledge of GS/OS.  I have also seen questions on other
tools that could be figured out from the manuals.  What I am trying to
say is, it is worth investing the time to look up the answers to questions
in the Toolbox Manuals.  If you can't find it, THEN ask the net.

Sorry to get on my soapbox,
