TIFFBUFFER(3TIFF)					     TIFFBUFFER(3TIFF)

NAME
       TIFFReadBufferSetup,  TIFFWriteBufferSetup - I/O	buffering control rou-
       tines

SYNOPSIS
       #include	<tiffio.h>

       int TIFFReadBufferSetup(TIFF *tif, tdata_t buffer, tsize_t size);
       int TIFFWriteBufferSetup(TIFF *tif, tdata_t buffer, tsize_t size);

DESCRIPTION
       The following routines are provided for client-control of the I/O  buf-
       fers  used  by the library. Applications	need never use these routines;
       they are	provided only for ``intelligent	clients'' that wish  to	 opti-
       mize  memory  usage and/or eliminate potential copy operations that can
       occur when working with images that have	data stored  without  compres-
       sion.

       TIFFReadBufferSetup  sets up the	data buffer used to read raw (encoded)
       data from a file. If the	specified pointer is NULL (zero), then a  buf-
       fer  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.  TIFFReadBufferSetup returns a non-zero value if the setup
       was successful and zero otherwise.

       TIFFWriteBufferSetup sets up the	data buffer used  to  write  raw  (en-
       coded) data to a	file. If the specified size 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 buffer	is NULL	(zero),	then a
       buffer of the appropriate size is  dynamically  allocated.   TIFFWrite-
       BufferSetup  returns  a	non-zero value if the setup was	successful and
       zero otherwise.

DIAGNOSTICS
       %s: No space for	data buffer at scanline	%ld.  TIFFReadBufferSetup  was
       unable to dynamically allocate space for	a data buffer.

       %s: No space for	output buffer.	TIFFWriteBufferSetup was unable	to dy-
       namically allocate space	for a data buffer.
