76	/* ¦ Make a copy of a directory structure in a new location.
77	The FSpDirectoryCopy function makes a copy of a directory structure in a
78	new location. If copyBufferPtr <> NIL, it points to a buffer of
79	copyBufferSize that is used to copy files data. The larger the
80	supplied buffer, the faster the copy. If copyBufferPtr = NIL, then this
81	routine allocates a buffer in the application heap. If you pass a
82	copy buffer to this routine, make its size a multiple of 512
83	($200) bytes for optimum performance.
84
85	srcSpec input: An FSSpec record specifying the directory to copy.
86	dstSpec input: An FSSpec record specifying destination directory
87	of the copy.
88	copyBufferPtr input: Points to a buffer of copyBufferSize that
89	is used the i/o buffer for the copy or
90	nil if you want DirectoryCopy to allocate its
91	own buffer in the application heap.
92	copyBufferSize input: The size of the buffer pointed to
93	by copyBufferPtr.
94	preflight input: If true, FSpDirectoryCopy makes sure there are
95	enough allocation blocks on the destination
96	volume to hold the directory's files before
97	starting the copy.
98	copyErrHandler input: A pointer to the routine you want called if an
99	error condition is detected during the copy, or
100	nil if you don't want to handle error conditions.
101	If you don't handle error conditions, the first
102	error will cause the copy to quit and
103	DirectoryCopy will return the error.
104	Error handling is recommended...
