<p><code>std::fpos_t</code> 是非数组完整对象类型，能用于存储（由 <span class="t-lc"><a href="cpp-io-c-fgetpos.html">std::fgetpos</a></span> ）及恢复（由 <span class="t-lc"><a href="cpp-io-c-fsetpos.html">std::fsetpos</a></span> ） C 流的位置与多字节分析状态（若存在）。</p>
|
|
<p>宽面向的 C 流的多字节分析状态以 <span class="t-lc"><a href="cpp-string-multibyte-mbstate_t.html">std::mbstate_t</a></span> 对象表示，其值由 <span class="t-lc"><a href="cpp-io-c-fgetpos.html">std::fgetpos</a></span> 作为 <code>std::fpos_t</code> 对象的值的一部分存储。</p>
