</div></div><p>This macro takes an exception object, records BOOST_CURRENT_FUNCTION, __FILE__ and __LINE__ in it, and forwards it to <span class="RenoLink"><a href="throw_exception.html">throw_exception</a></span>. To recover this information at the catch site, use <span class="RenoLink"><a href="get_error_info.html">get_error_info</a></span>; the information is also included in the message returned by <span class="RenoLink"><a href="diagnostic_information.html">diagnostic_information</a></span>.</p>
