<p>类型 <code>path</code> 的对象表示文件系统上的路径。只有路径的语法外观得到处理：路径名可能表示不存在的路径，或甚至不允许存在于当前文件系统或操作系统的路径。</p>
|
|
<p>路径名拥有下列语法：</p>
|
|
<ol>
|
|
<li><span class="t-spar">根名</span><span class="t-mark">(可选)</span> ：标识具有多根的文件系统（如 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="st0">"C:"</span></span></span> 或 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="st0">"//myserver"</span></span></span> ）的根。有歧义的情况下，将组成合法 <span class="t-spar">根名</span> 的最长序列当做 <span class="t-spar">根名</span> 。标准库可以在 OS API 所了解的 <span class="t-spar">根名</span> 外，定义额外的 <span class="t-spar">根名</span> 。</li>
|
|
<li><span class="t-spar">根目录</span><span class="t-mark">(可选)</span> ：目录分隔符，若存在，则标记此路径为<i>绝对</i>。若缺失（且异于根名的首元素是文件名），则路径为<i>相对</i>且要求另一路径作为解决此文件名的起始位置。</li>
|
|
<li>零或多个下列者：</li>
|
|
</ol>
|
|
<dl>
|
|
<dd>
|
|
<ul>
|
|
<li><span class="t-spar">文件名</span> ：不由目录分隔符或偏好目录分隔符组成的字符序列（操作系统或文件系统可能加上附加限制）。此名称可能标识一个文件、硬链接或目录。辨别二种特殊的 <span class="t-spar">文件名</span> ：</li>
|
|
</ul>
|
|
<dl>
|
|
<dd>
|
|
<ul>
|
|
<li><span class="t-spar">点</span> ：由单个点字符 <span class="t-c"><span class="mw-geshi cpp source-cpp">.</span></span> 构成的文件名是指代当前目录的目录名</li>
|
|
<li><span class="t-spar">点点</span> ：由二个点字符 <span class="t-c"><span class="mw-geshi cpp source-cpp">..</span></span> 构成的文件名是指代父目录的目录名。</li>
|
|
</ul>
|
|
</dd>
|
|
</dl>
|
|
<ul>
|
|
<li><span class="t-spar">目录分隔符</span> ：正斜杠字符 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="sy2">/</span></span></span> 或作为 <code>path::preferred_separator</code> 提供的另一种字符。若重复此字符，则它被处理成单个目录分隔符： <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="sy2">/</span>usr<span class="co1">///////lib</span></span></span> 与 <span class="t-c"><span class="mw-geshi cpp source-cpp"><span class="sy2">/</span>usr<span class="sy2">/</span>lib</span></span> 相同</li>
|
|
</ul>
|
|
</dd>
|
|
</dl>
|
|
<p>路径能以下列算法<i>正常化</i>：</p>
|
|
<ol>
|
|
<li>若路径为空，则停止（空路径的正常形式是空路径）</li>
|
|
<li>替换每个 <span class="t-spar">目录分隔符</span> （可以由多重斜杠组成）为单个 <code>path::preferred_separator</code> 。</li>
|
|
<li>替换 <span class="t-spar">根名</span> 中的每个斜杠字符为 <code>path::preferred_separator</code> 。</li>
|
|
<li>移除每个 <span class="t-spar">点</span> 和立即后随的 <span class="t-spar">目录分隔符</span> 。</li>
|
|
<li>移除每个立即后随 <span class="t-spar">目录分隔符</span> 和一个 <span class="t-spar">点点</span> 的非 <span class="t-spar">点点</span> 文件名，还有立即跟随的 <span class="t-spar">目录分隔符</span> 。</li>
|
|
<li>若存在 <span class="t-spar">根目录</span> ，则移除立即跟随它们的所有 <span class="t-spar">点点</span> 及任何 <span class="t-spar">目录分隔符</span> 。</li>
|
|
<li>若最终文件名是 <span class="t-spar">点点</span> ，则移除任何尾随的 <span class="t-spar">目录分隔符</span> 。</li>
|
|
<li>若路径为空，则添加一个 <span class="t-spar">点</span> （ <span class="t-c"><span class="mw-geshi cpp source-cpp">.<span class="sy2">/</span></span></span> 的正常形式是 <span class="t-c"><span class="mw-geshi cpp source-cpp">.</span></span> ）</li>
|
|
</ol>
|
|
<p>路径可由 <span class="t-lc"><a href="cpp-filesystem-path-begin.html">begin()</a></span> 与 <span class="t-lc"><a href="cpp-filesystem-path-begin.html">end()</a></span> 函数返回的迭代器逐元素遍历，这会以通用格式查看路径，并在根名、根目录及后继文件名元素上迭代（跳过目录分隔符，除了标识根目录者）。若路径中的最后元素是目录分隔符，则最后的迭代器将解引用为空元素。</p>
|
|
<p>调用任何的 <code>path</code> 非 const 成员函数会令所有引用该对象元素的迭代器非法。</p>
|
|
<p>若 OS 使用异于上述可移植<i>通用</i>语法的<i>原生</i>语法，则库函数被定义为接受“受检测格式”，以接受两种格式的路径名：当且仅当受检测格式匹配通用格式，但不为操作系统作为原生路径接受，才采用受检测格式参数。原生格式在目录路径名和文件路径名有别的 OS 上，若通用路径名以目录分隔符终止，则将它当做目录路径，否则当做常规文件。</p>
|
|
<p>任何情况下， path 类表型如同它以原生格式存储路径名，并自动于所需场合转换它为通用格式（每个成员函数都指定它转译的路径格式）</p>
|
|
<p>POSIX 系统上，通用格式就是原生格式，并且没有必要区别或转换它们。</p>
|
|
<p>路径可隐式转换自及转换成 <span class="t-lc"><a href="cpp-string-basic_string.html">std::basic_string</a></span> ，这使得在文件 API 上使用它们可行，例如作为到 <span class="t-lc"><a href="cpp-io-basic_ifstream-open.html">std::ifstream::open</a></span> 的参数</p>
