NAME
       TIFFbuffer - I/O buffering control routines

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
       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.
