/* � Prototype for the CopyErrProc function DirectoryCopy calls.
This is the prototype for the CopyErrProc function DirectoryCopy

CopyErrProc returns false, then DirectoryCopy attempts to continue with
the directory copy operation. If CopyErrProc returns true, then
DirectoryCopy stops the directory copy operation.
error input: The error result code that caused CopyErrProc to
be called.
failedOperation input: The operation that returned an error to
DirectoryCopy.
srcVRefNum input: Source volume specification.
srcDirID input: Source directory ID.
srcName input: Source file or directory name, or nil if
srcDirID specifies the directory.
dstVRefNum input: Destination volume specification.
dstDirID input: Destination directory ID.
dstName input: Destination file or directory name, or nil if
dstDirID specifies the directory.

/* � Make a copy of a directory structure in a new location.
The FSpDirectoryCopy function makes a copy of a directory structure in a
new location. If copyBufferPtr <> NIL, it points to a buffer of
copyBufferSize that is used to copy files data. The larger the
supplied buffer, the faster the copy. If copyBufferPtr = NIL, then this
routine allocates a buffer in the application heap. If you pass a
copy buffer to this routine, make its size a multiple of 512
($200) bytes for optimum performance.
srcSpec input: An FSSpec record specifying the directory to copy.
dstSpec input: An FSSpec record specifying destination directory
of the copy.
copyBufferPtr input: Points to a buffer of copyBufferSize that
is used the i/o buffer for the copy or
nil if you want DirectoryCopy to allocate its
own buffer in the application heap.
copyBufferSize input: The size of the buffer pointed to
by copyBufferPtr.
preflight input: If true, FSpDirectoryCopy makes sure there are
enough allocation blocks on the destination
volume to hold the directory's files before
starting the copy.
copyErrHandler input: A pointer to the routine you want called if an
error condition is detected during the copy, or
nil if you don't want to handle error conditions.
If you don't handle error conditions, the first
error will cause the copy to quit and
DirectoryCopy will return the error.
Error handling is recommended...
