+.SH DESCRIPTION
+These routines are provided for writing portable software that uses
+.IR libtiff ;
+they hide any memory-management related issues, such as dealing with
+segmented architectures found on 16-bit machines.
+.PP
+.I _TIFFmalloc
+and
+.I _TIFFrealloc
+are used to dynamically allocate and reallocate memory used by
+.IR libtiff ;
+such as memory passed into the I/O routines.
+Memory allocated through these interfaces is released back to the
+system using the
+.I _TIFFfree
+routine.
+.PP
+Memory allocated through one of the above interfaces can be set to
+a known value using
+.IR _TIFFmemset ,
+copied to another memory location using
+.IR _TIFFmemcpy ,
+or compared for equality using
+.IR _TIFFmemcmp .
+These routines conform to the equivalent
+.SM ANSI
+C routines:
+.IR memset ,
+.IR memcpy ,
+and
+.IR memcmp ,
+repsectively.
+.SH DIAGNOSTICS
+None.
+.SH "SEE ALSO"
+.IR libtiff (3T),
+.IR malloc (3C),
+.IR memory (3C)
