In the 4.5 release, this functionality has been replaced by a general-purpose event notification callback function, set with the <a href="../../api_c/env_event_notify.html">DB_ENV->set_event_notify</a> method. Applications should be updated to replace DB_ENV->set_paniccall and DB->set_paniccall calls with a call to <a href="../../api_c/env_event_notify.html">DB_ENV->set_event_notify</a>. This also requires the callback function itself change, as the callback signatures are different.</p> <p>The DB_ENV->set_paniccall and DB->set_paniccall calls are expected to be removed in a future release of Berkeley DB.</p> <table width="100%"><tr><td><br></td><td align=right><a href="../upgrade.4.5/memp.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../upgrade.4.5/pagesize.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1>Copyright (c) 1996,2008 Oracle.
