The <code class="methodname">DB->get_byteswapped()</code> method returns
whether the underlying database
files were created on an architecture of the same byte order as the
current one, or if they were not (that is, big-endian on a
little-endian machine, or vice versa). This information may be used to
determine whether application data needs to be adjusted for this
architecture or not.

<p>
The <code class="methodname">DB->get_byteswapped()</code> method may not be called before the
<a class="xref" href="dbopen.html" title="DB->open()">DB->open()</a> method is called.

<p>
The <code class="methodname">DB->get_byteswapped()</code> <span>
