| 35 | </div><h4>Effects:</h4> |
| 36 | <div><ul><li> If BOOST_NO_EXCEPTIONS is not defined, boost::<span class="RenoLink">throw_exception</span>(e) throws an exception of unspecified type that derives publicly from E and from boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.</li> |
| 37 | <li> If BOOST_NO_EXCEPTIONS is defined, the function is left undefined, and the user is expected to supply an appropriate definition. Callers of <span class="RenoLink">throw_exception</span> are allowed to assume that the function never returns; therefore, if the user-defined <span class="RenoLink">throw_exception</span> returns, the behavior is undefined.</li> |
| 38 | </ul></div> |
| 39 | <h4>Requirements:</h4> |
| 40 | <p>E must derive publicly from std::exception. E may or may not derive from boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.</p> |
| 41 | <h4>Notes:</h4> |
| 42 | <div><ul><li> The emitted exception can be intercepted as E &, std::exception &, or boost::exception &.</li> |
| 43 | <li> The emitted exception supports boost::<span class="RenoLink"><a href="exception_ptr.html">exception_ptr</a></span>.</li> |
| 44 | <li> If BOOST_EXCEPTION_DISABLE is defined and BOOST_NO_EXCEPTIONS is not defined, boost::<span class="RenoLink">throw_exception</span>(e) equivalent to throw e.</li> |
