+<H2>DESCRIPTION</H2>
+
+The following routines are provided for client-control of the
+I/O buffers used by the library.
+Applications need never use these routines; they are provided only
+for ``intelligent clients'' that wish to optimize memory usage and/or
+eliminate potential copy operations that can occur when working with
+images that have data stored without compression.
+<P>
+
+<I>TIFFReadBufferSetup</I>
+
+sets up the data buffer used to read raw (encoded) data from a file.
+If the specified pointer is
+<FONT SIZE="-1">NULL</FONT>
+(zero), then a buffer of the appropriate size is allocated.
+Otherwise the caller must guarantee that the buffer is large
+enough to hold any individual strip of raw data.
+<I>TIFFReadBufferSetup</I>
+
+returns a non-zero value if the setup was successful and zero otherwise.
+<P>
+
+<I>TIFFWriteBufferSetup</I>
+
+sets up the data buffer used to write raw (encoded) data to a file.
+If the specified
+<I>size</I>
+
+is -1 then the buffer size is selected to hold a complete
+tile or strip, or at least 8 kilobytes, whichever is greater.
+If the specified
+<I>buffer</I>
+
+is 
+<FONT SIZE="-1">NULL</FONT>
+(zero), then a buffer of the appropriate size is dynamically allocated.
+<I>TIFFWriteBufferSetup</I>
+
+returns a non-zero value if the setup was successful and zero otherwise.
