<h4>Returns:</h4>
|

<div><ul><li> An <tt><span class="RenoLink"><a href="exception_ptr.html">exception_ptr</a></span></tt> that refers to the currently handled exception or a copy of the currently handled exception.</li>

<li> If the function needs to allocate memory and the attempt fails, it returns an <tt><span class="RenoLink"><a href="exception_ptr.html">exception_ptr</a></span></tt> that refers to an instance of <tt>std::bad_alloc</tt>.</li>

<li> Correct implementation of <tt><span class="RenoLink"><a href="current_exception.html">current_exception</a></span>()</tt> may require compiler support, unless <tt><span class="RenoLink"><a href="enable_current_exception.html">enable_current_exception</a></span>()</tt> is used at the time the currently handled exception object was passed to <tt>throw</tt>.

In this case, if the original exception object derives from <tt>boost::<span class="RenoLink"><a href="exception.html">exception</a></span></tt>, then the <tt>boost::<span class="RenoLink"><a href="exception.html">exception</a></span></tt> sub-object of the <tt><span class="RenoLink"><a href="unknown_exception.html">unknown_exception</a></span></tt> object is initialized by the <tt>boost::<span class="RenoLink"><a href="exception.html">exception</a></span></tt> copy constructor.</li>
