NAME

       TIFFReadBufferSetup, TIFFWriteBufferSetup - I/O buffering control routines

SYNOPSIS

       #include <tiffio.h>
       int TIFFReadBufferSetup(TIFF*, tdata_t buffer, tsize_t size);
       int TIFFWriteBufferSetup(TIFF*, tdata_t buffer, tsize_t size);

DESCRIPTION

       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.

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

       TIFFWriteBufferSetup  sets up the data buffer used to write raw (encoded) 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.  TIFFWriteBufferSetup 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 dynamically allocate space for a data buffer.
