TIFFbuffer - I/O buffering control routines
#include <tiffio.h>
int TIFFReadBufferSetup(TIFF *tif, void *buffer, tmsize_t size)
int TIFFWriteBufferSetup(TIFF *tif, void *buffer, tmsize_t size)
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.

SYNOPSIS
#include <tiffio.h>

int TIFFWriteBufferSetup(TIFF *tif, void *buffer, tmsize_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.
