 * the first element of the array with n elements each elem_size_bytes big.  cmp_fn is
 * a comparison function that should be able to take in pointers to two elements in the
 * array and return 0 if they should be considered equal, < 0 if the first should be considered
 * to come before the second, or > 0 if the first should be considered to come after the second.
