102 This is the prototype for the CallCopyObjectFilterProc function which
103 is called once for each file and directory found by FSCopyObject.
104 The CallCopyObjectFilterProc can use the read-only data it receives for
105 whatever it wants.
106
107 The result of the CallCopyObjectFilterProc function indicates if
108 iteration should be stopped. To stop iteration, return true; to continue
109 iteration, return false.
110
111 The yourDataPtr parameter can point to whatever data structure you might
112 want to access from within the CallCopyObjectFilterProc.
113
114 containerChanged --> Set to true if the container's contents changed
115 during iteration.
116 currentLevel --> The current recursion level into the container.
117 1 = the container, 2 = the container's immediate
118 subdirectories, etc.
119 currentOSErr --> The current error code, shows the results of the
120 copy of the current object (ref)
121 catalogInfo --> The catalog information for the current object.
122 Only the fields requested by the whichInfo
123 parameter passed to FSIterateContainer are valid.
124 ref --> The FSRef to the current object.
125 spec --> The FSSpec to the current object if the wantFSSpec
126 parameter passed to FSCopyObject is true.
127 name --> The name of the current object if the wantName
128 parameter passed to FSCopyObject is true.
129 yourDataPtr --> An optional pointer to whatever data structure you
130 might want to access from within the
131 CallCopyObjectFilterProc.
132 result <-- To stop iteration, return true; to continue
133 iteration, return false.

163 The FSCopyObject function takes a source object (can be a file or directory)
164 and copies it (and its contents if it's a directory) to the new destination
165 directory.
166
167 It will call your CopyObjectFilterProcPtr once for each file/directory

169
170 The maxLevels parameter is only used when the object is a directory,
171 ignored otherwise.
172 It lets you control how deep the recursion goes.
173 If maxLevels is 1, FSCopyObject only scans the specified directory;
174 if maxLevels is 2, FSCopyObject scans the specified directory and
175 one subdirectory below the specified directory; etc. Set maxLevels to
176 zero to scan all levels.

193 want called once for each object found
