116 The FilteredDirectoryCopy function makes a copy of a directory
117 structure in a new location. If copyBufferPtr <> NIL, it points to
118 a buffer of copyBufferSize that is used to copy files data. The
119 larger the supplied buffer, the faster the copy. If
120 copyBufferPtr = NIL, then this routine allocates a buffer in the
121 application heap. If you pass a copy buffer to this routine, make
122 its size a multiple of 512 ($200) bytes for optimum performance.
123
124 The optional copyFilterProc parameter lets a routine you define
125 decide what files or directories are copied to the destination.
126
127 FilteredDirectoryCopy normally creates a new directory *in* the
128 specified destination directory and copies the source directory's
129 content into the new directory. However, if root parent directory
130 (fsRtParID) is passed as the dstDirID parameter and NULL is
131 passed as the dstName parameter, DirectoryCopy renames the
132 destination volume to the source directory's name (truncating
133 if the name is longer than 27 characters) and copies the source
134 directory's content into the destination volume's root directory.
135 This special case is supported by FilteredDirectoryCopy, but
136 not by FSpFilteredDirectoryCopy since with FSpFilteredDirectoryCopy,
137 the dstName parameter can not be NULL.
138
139 srcVRefNum input: Source volume specification.
140 srcDirID input: Source directory ID.
141 srcName input: Source directory name, or nil if
142 srcDirID specifies the directory.

144 dstDirID input: Destination directory ID.
145 dstName input: Destination directory name, or nil if
146 dstDirID specifies the directory.
147 copyBufferPtr input: Points to a buffer of copyBufferSize that
148 is used the i/o buffer for the copy or
149 nil if you want DirectoryCopy to allocate its
150 own buffer in the application heap.
151 copyBufferSize input: The size of the buffer pointed to
152 by copyBufferPtr.
153 preflight input: If true, DirectoryCopy makes sure there are
154 enough allocation blocks on the destination
155 volume to hold the directory's files before
156 starting the copy.
157 copyErrHandler input: A pointer to the routine you want called if an
158 error condition is detected during the copy, or
159 nil if you don't want to handle error conditions.
160 If you don't handle error conditions, the first
161 error will cause the copy to quit and
162 DirectoryCopy will return the error.
163 Error handling is recommended...
164 copyFilterProc input: A pointer to the filter routine you want called
165 for each item in the source directory, or NULL
166 if you don't want to filter.
