<H2>DESCRIPTION</H2>

These routines are provided for writing portable software that uses 
<I>libtiff</I>;

they hide any memory-management related issues, such as dealing with
segmented architectures found on 16-bit machines.
<P>

<I>_TIFFmalloc</I>

and
<I>_TIFFrealloc</I>

are used to dynamically allocate and reallocate memory used by 
<I>libtiff</I>;

such as memory passed into the I/O routines.
Memory allocated through these interfaces is released back to the
system using the
<I>_TIFFfree</I>

routine.
<P>

Memory allocated through one of the above interfaces can be set to
a known value using
<I>_TIFFmemset</I>,

copied to another memory location using
<I>_TIFFmemcpy</I>,

or compared for equality using 
<I>_TIFFmemcmp</I>.

These routines conform to the equivalent
<FONT SIZE="-1">ANSI</FONT>
C routines: 
<I>memset</I>,

<I>memcpy</I>,

and
<I>memcmp</I>,

repsectively.
<A NAME="lbAE">&nbsp;</A>
