In such cases, the Berkeley DB methods will either return <a href="../../db42-devel-4.2.52/ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> or throw a <a href="../../db42-devel-4.2.52/api_cxx/runrec_class.html">DbRunRecoveryException</a>, depending on the API configuration. It is often easier to simply exit the application when such errors occur rather than gracefully return up the stack. The Db::set_paniccall method specifies a function to be called when <a href="../../db42-devel-4.2.52/ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> is about to be returned or <a href="../../db42-devel-4.2.52/api_cxx/runrec_class.html">DbRunRecoveryException</a> is about to be thrown from a Berkeley DB method.</p> <p>For <a href="../../db42-devel-4.2.52/api_cxx/db_class.html">Db</a> handles opened inside of Berkeley DB environments, calling the Db::set_paniccall method affects the entire environment and is equivalent to calling the <a href="../../db42-devel-4.2.52/api_cxx/env_set_paniccall.html">DbEnv::set_paniccall</a> method.</p> <p>The Db::set_paniccall method may be called at any time during the life of the application.</p> <p>The Db::set_paniccall 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>db_panic_fcn</b><dd> The <b>db_panic_fcn</b> parameter is the application-specified function called in the case of a database environment panic.
