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
|
|
whatever it wants.
|
|

The result of the CallCopyObjectFilterProc function indicates if
|
|
iteration should be stopped. To stop iteration, return true; to continue
|

iteration, return false.

|
The yourDataPtr parameter can point to whatever data structure you might
|
|
want to access from within the CallCopyObjectFilterProc.
|
|
|
|
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

one subdirectory below the specified directory; etc. Set maxLevels to
