<h3 align=center>Release 4.3: DB_ENV->set_errcall, DB->set_errcall</h3>
<p>The signature of the error callback passed to the
<a href="../../api_c/env_set_errcall.html">DB_ENV->set_errcall</a> and <a href="../../api_c/db_set_errcall.html">DB->set_errcall</a> methods has changed in
the 4.3 release. For example, if you previously had a function such as
this:</p>
<blockquote><pre>void handle_db_error(const char *prefix, char *message);</pre></blockquote>
<p>it should be changed to this:</p>
<blockquote><pre>void handle_db_error(const DB_ENV *dbenv,
const char *prefix, const char *message);</pre></blockquote>
<p>This change adds the <a href="../../api_c/env_class.html">DB_ENV</a> handle to provide database
environment context for the callback function, and incidentally makes
it clear the message parameter cannot be changed by the callback.</p>
