<h3>Description: Db::get_byteswapped</h3>
<p>The Db::get_byteswapped method returns
if 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>
<p>The Db::get_byteswapped method may not be called before the <a href="../../db42-devel-4.2.52/api_cxx/db_open.html">Db::open</a> method has been
called.</p>
<p>The Db::get_byteswapped 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.
</p>
<h3>Parameters</h3>
<p><dl compact>
<p><dt><b>isswapped</b><dd>
If the underlying database files were created on an architecture of the
same byte order as the current one. 0 is stored into the memory location
referenced by <b>isswapped</b>.  If the underlying database files were
created on an architecture of a different byte order as the current one,
1 is stored into the memory location referenced by <b>isswapped</b>.
</dl>
<h3>Errors</h3>
<p>The Db::get_byteswapped method
may fail and throw
<a href="../../db42-devel-4.2.52/api_cxx/except_class.html">DbException</a>,
encapsulating one of the following non-zero errors, or return one of
the following non-zero errors:</p>
<p><dl compact>
<p><dt>EINVAL<dd>If the method was called before <a href="../../db42-devel-4.2.52/api_cxx/db_open.html">Db::open</a> was called; or if an
invalid flag value or parameter was specified.
