    int main ()
    {
        int numbers[] = {9, 2, 4, 8};
        pair int*, ptrdiff_t result = get_temporary_bufferint(4);
        if (result.second  0)
        {
            uninitialized_copy (numbers, numbers + result.second, result.first);
            sort (result.first, result.first + result.second);
            for (int i = 0; i  result.second; i++)
                cout  result.first[i]  " ";
            return_temporary_buffer (result.first);
        }
