Set the byte order for integers in the stored database metadata. The
host byte order of the machine where the Berkeley DB library was
compiled will be used if no byte order is set.

the byte ordering of the application data stored in the database, and
applications are responsible for maintaining any necessary
ordering.</strong></span>

The <code class="methodname">Db::set_lorder()</code> method configures a database, not only
operations performed using the specified <a class="link" href="db.html" title="Chapter 2. The Db Handle">Db</a>
handle.
</p>
<p>
The <code class="methodname">Db::set_lorder()</code> method may not be called after the
<a class="xref" href="dbopen.html" title="Db::open()">Db::open()</a> method is called. If
the database already exists when <a class="xref" href="dbopen.html" title="Db::open()">Db::open()</a>
is called, the information specified to <code class="methodname">Db::set_lorder()</code> will be ignored.
</p>
<p>
If creating additional databases in a single physical file,
information specified to
<code class="methodname">Db::set_lorder()</code> will be ignored and the
byte order of the existing databases will be used.
</p>
<p>
The <code class="methodname">Db::set_lorder()</code> <span>
<span>
method either returns a non-zero error value or throws an
exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
