/* ¦ Make a copy of a directory structure in a new location with item filtering.
The FilteredDirectoryCopy 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.
The optional copyFilterProc parameter lets a routine you define
decide what files or directories are copied to the destination.
FilteredDirectoryCopy normally creates a new directory *in* the
specified destination directory and copies the source directory's
content into the new directory. However, if root parent directory
(fsRtParID) is passed as the dstDirID parameter and NULL is
passed as the dstName parameter, DirectoryCopy renames the
destination volume to the source directory's name (truncating
if the name is longer than 27 characters) and copies the source
directory's content into the destination volume's root directory.
This special case is supported by FilteredDirectoryCopy, but
not by FSpFilteredDirectoryCopy since with FSpFilteredDirectoryCopy,
the dstName parameter can not be NULL.
srcVRefNum input: Source volume specification.
srcDirID input: Source directory ID.
srcName input: Source directory name, or nil if
srcDirID specifies the directory.
dstVRefNum input: Destination volume specification.
dstDirID input: Destination directory ID.
dstName input: Destination directory name, or nil if
dstDirID specifies the directory.
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, DirectoryCopy 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...
copyFilterProc input: A pointer to the filter routine you want called
for each item in the source directory, or NULL
if you don't want to filter.
