#pragma mark CopyObjectFilterProcPtr
/*
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
parameter passed to FSIterateContainer are valid.
ref --> The FSRef to the current object.
spec --> The FSSpec to the current object if the wantFSSpec
parameter passed to FSCopyObject is true.
name --> The name of the current object if the wantName
parameter passed to FSCopyObject is true.
yourDataPtr --> An optional pointer to whatever data structure you
might want to access from within the
CallCopyObjectFilterProc.
result <-- To stop iteration, return true; to continue
iteration, return false.

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.
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
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.
iterateFilter --> A pointer to the CopyObjectFilterProc you
want called once for each object found
by FSCopyObject.

might want to access from within the
CopyObjectFilterProc.

#pragma mark FSDeleteObjects
/*
The FSDeleteObjects function takes an FSRef to a file or directory
and attempts to delete it. If the object is a directory, all files
and subdirectories in the specified directory are deleted. If a
locked file or directory is encountered, it is unlocked and then
deleted. After deleting the directory's contents, the directory
is deleted. If any unexpected errors are encountered,
FSDeleteContainer quits and returns to the caller.
source --> FSRef to an object (can be file or directory).
