 * This file is part of libdyn.a, the C Dynamic Object library.  It
 * contains the source code for the internal function _DynRealloc().
 * There are no restrictions on this code; however, if you make any
 * changes, I request that you document them so that I do not get
 * credit or blame for your modifications.
 * Written by Barr3y Jaspan, Student Information Processing Board (SIPB)

#include <stdio.h>

#include "dynP.h"

 * Ideally, this function should not be called from outside the
 * library.  However, nothing will break if it is.
