DB->get_byteswapped(DB *db, int *isswapped);
</pre></h3>
<h1>Description</h1>
<p>The DB->get_byteswapped method
stores 0 into the memory location referenced by <b>isswapped</b>
if the underlying database files were created on an architecture of the
same byte order as the current one, and
stores 1 into the memory location referenced by <b>isswapped</b>
if they were not (that is, big-endian on a little-endian machine, or
vice versa). This field may be used to determine whether application
data needs to be adjusted for this architecture or not.
<p>The DB->get_byteswapped interface may not be called before the <a href="../api_c/db_open.html">DB->open</a>
interface has been called.
<h1>Errors</h1>
<p>The DB->get_byteswapped method may fail and return a non-zero error for the following conditions:
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>Called before <a href="../api_c/db_open.html">DB->open</a> was called.
</dl>
<p>The DB->get_byteswapped method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB->get_byteswapped method may fail and
return <a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
