TIFFbuffer(3TIFF)

NAME
     TIFFReadBufferSetup, TIFFWriteBufferSetup - 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.
