| 32 | }</pre> | |
| 33 | </div><h4>Requirements:</h4> | |
| 34 | <div><ul><li> ErrorInfo must be an instance of the <span class="RenoLink"><a href="error_info.html">error_info</a></span> template.</li> | |
| 35 | <li> E must be polymorphic.</li> | |
| 36 | </ul></div> | |
| 37 | <h4>Returns:</h4> | |
| 38 | <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> | |
| 39 | <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> | |
| 40 | </ul></div> | |
| 41 | <h4>Throws:</h4> | |
| 42 | <p>Nothing.</p> | |
| 43 | <h4>Note:</h4> | |
| 44 | <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> | |
