<p>If programmers define this configuration macro on a C++11 compiler for which the Boost.Config macro <code class="computeroutput">BOOST_NO_CXX11_LAMBDAS</code> is not defined, the  <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> and <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> macros will use C++11 lambda functions to declare scope exits. By default this macro is not defined.</p>
<p><span class="bold"><strong>Warning:</strong></span> When scope exits are implemented using lambda functions, the syntax of the capture list follows the exact same syntax of C++11 lambda captures which is in general different from the legacy capture syntax of this library. For example, C++11 lambdas require to capture data members by capturing the object <code class="computeroutput">this</code> while this library always allowed to capture data members directly. Therefore, when this configuration macro is defined,  <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT.html" title="Macro BOOST_SCOPE_EXIT">BOOST_SCOPE_EXIT</a></code> and <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_TPL.html" title="Macro BOOST_SCOPE_EXIT_TPL">BOOST_SCOPE_EXIT_TPL</a></code> are no longer backward compatible (and this is why this macro is not defined by default).</p>

<p><span class="bold"><strong>Note:</strong></span> This configuration macro does not control the definition of  <code class="computeroutput"><a class="link" href="BOOST_SCOPE_EXIT_ALL.html" title="Macro BOOST_SCOPE_EXIT_ALL">BOOST_SCOPE_EXIT_ALL</a></code> which is always and automatically defined on compilers that support C++11 lambda functions.</p>
