<p><code>std::terminate_handler</code> 是函数指针类型（指向不接收参数且返回 void 的函数），这些函数为 <span class="t-lc"><a href="cpp-error-set_terminate.html">std::set_terminate</a></span> 安装，为 <span class="t-lc"><a href="cpp-error-get_terminate.html">std::get_terminate</a></span> 查询，并为 <span class="t-lc"><a href="cpp-error-terminate.html">std::terminate</a></span> 调用。</p>
|
|
<p>C++ 实现提供默认的 <code>std::terminate_handler</code> 函数，它调用 <span class="t-c"><span class="mw-geshi cpp source-cpp"><a href="cpp-utility-program-abort.html"><span class="kw965">std::<span class="me2">abort</span></span></a><span class="br0">(</span><span class="br0">)</span></span></span> 。若安装空指针值（以 <span class="t-lc"><a href="cpp-error-set_terminate.html">std::set_terminate</a></span> 的手段），则实现可以恢复默认安装的处理函数。</p>
