|
|
</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>
