<p><code>std::error_condition</code> 是独立于平台的错误码。类似于 <span class="t-lc"><a href="cpp-error-error_code.html">std::error_code</a></span> ，它为整数值和 <span class="t-lc"><a href="cpp-error-error_category.html">std::error_category</a></span> 所唯一标识，但不同于 <span class="t-lc"><a href="cpp-error-error_code.html">std::error_code</a></span> ，该值不依赖平台。</p>
|
|
<p>典型的实现保有整数数据成员（该值）和指向一个 <span class="t-lc"><a href="cpp-error-error_category.html">std::error_category</a></span> 的指针。</p>
