| </div><h4>Requirements:</h4> |
| <div><ul><li> ErrorInfo must be an instance of the <span class="RenoLink"><a href="error_info.html">error_info</a></span> template.</li> |
| <li> E must be polymorphic.</li> |
| </ul></div> |
| <h4>Returns:</h4> |
| <div><ul><li> If dynamic_cast<boost::<span class="RenoLink"><a href="exception.html">exception</a></span> const *>(&x) is 0, or if x does not store an object of type ErrorInfo, the returned value is null.</li> |
| <li> Otherwise, the returned pointer points to the stored value (use <span class="RenoLink"><a href="exception_operator_shl.html">operator<<</a></span> to store values in exception objects.) When x is destroyed, any pointers returned by <span class="RenoLink">get_error_info</span> become invalid.</li> |
| </ul></div> |
| <h4>Throws:</h4> |
| <p>Nothing.</p> |
| <h4>Note:</h4> |
| <p>The interface of <span class="RenoLink">get_error_info</span> may be affected by the build <span class="RenoLink"><a href="configuration_macros.html">configuration macros</a></span>.</p> |
