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.
|

want to access from within the CallCopyObjectFilterProc.

containerChanged --> Set to true if the container's contents changed

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.
