This is the prototype for the CallCopyObjectFilterProc function which
is called once for each file and directory found by FSCopyObject.
The CallCopyObjectFilterProc can use the read-only data it receives for

The result of the CallCopyObjectFilterProc function indicates if
the copy should be stopped. To stop the copy, return an error; to continue
the copy, return noErr.

want to access from within the CallCopyObjectFilterProc.
Note: If an error had occured during the copy of the current object

containerChanged --> Set to true if the container's contents changed
during iteration.
currentLevel --> The current recursion level into the container.
1 = the container, 2 = the container's immediate
subdirectories, etc.
currentOSErr --> The current error code, shows the results of the
copy of the current object (ref)
catalogInfo --> The catalog information for the current object.
Only the fields requested by the whichInfo
parameter passed to FSIterateContainer are valid.

The FSCopyObject function takes a source object (can be a file or directory)
and copies it (and its contents if it's a directory) to the new destination
directory.
It will call your CopyObjectFilterProcPtr once for each object copied
The maxLevels parameter is only used when the object is a directory,
ignored otherwise.
It lets you control how deep the recursion goes.
If maxLevels is 1, FSCopyObject only scans the specified directory;
if maxLevels is 2, FSCopyObject scans the specified directory and
one subdirectory below the specified directory; etc. Set maxLevels to
zero to scan all levels.
The yourDataPtr parameter can point to whatever data structure you might
want to access from within your CopyObjectFilterProcPtr.
source --> The FSRef to the object you want to copy
destDir --> The FSRef to the directory you wish to copy source to
maxLevels --> Maximum number of directory levels to scan or
zero to scan all directory levels, ignored if the
object is a file
whichInfo --> The fields of the FSCatalogInfo you wish passed
to you in your CopyObjectFilterProc
dupeAction --> The action to take if an object of the same name exists
in the destination
newName --> The name you want the new object to have. If you pass
in NULL, the source object name will be used.
wantFSSpec --> Set to true if you want the FSSpec to each
object passed to your CopyObjectFilterProc.
wantName --> Set to true if you want the name of each
object passed to your CopyObjectFilterProc.
filterProcPtr --> A pointer to the CopyObjectFilterProc you
want called once for each object found
by FSCopyObject.
yourDataPtr --> An optional pointer to whatever data structure you
might want to access from within the
CopyObjectFilterProc.
newObjectRef --> An optional pointer to an FSRef that, on return,
references the new object. If you don't want this
