The <code class="classname">DB_LSN</code> object is a <span class="emphasis"><em>log sequence number</em></span>
which specifies a unique location in a log file. A <code class="classname">DB_LSN</code>
consists of two unsigned 32-bit integers -- one specifies the log file number, and the other
specifies an offset in the log file.
