    <p>Copies a directory from <tt class="docutils literal"><span class="pre"><span class="Identifier">source</span></span></tt> to <tt class="docutils literal"><span class="pre"><span class="Identifier">dest</span></span></tt> preserving file permissions.</p>
<p>On non-Windows OSes, symlinks are copied as symlinks. On Windows, symlinks are skipped.</p>
<p>If <tt class="docutils literal"><span class="pre"><span class="Identifier">skipSpecial</span></span></tt> is true, then (besides all directories) only <em>regular</em> files (<strong>without</strong> special &quot;file&quot; objects like FIFOs, device files, etc) will be copied on Unix.</p>
<p>If this fails, <tt class="docutils literal"><span class="pre"><span class="Identifier">OSError</span></span></tt> is raised. This is a wrapper proc around <a class="reference internal nimdoc" title="proc copyDir(source, dest: string; skipSpecial = false)" href="#copyDir,string,string">copyDir</a> and <a class="reference external" href="./osfiles.html#copyFileWithPermissions,string,string">osfiles: copyFileWithPermissions</a> procs on non-Windows platforms.</p>
<p>On Windows this proc is just a wrapper for <a class="reference internal nimdoc" title="proc copyDir(source, dest: string; skipSpecial = false)" href="#copyDir,string,string">copyDir proc</a> since that proc already copies attributes.</p>
<p>On non-Windows systems permissions are copied after the file or directory itself has been copied, which won't happen atomically and could lead to a race condition. If <tt class="docutils literal"><span class="pre"><span class="Identifier">ignorePermissionErrors</span></span></tt> is true (default), errors while reading/setting file attributes will be ignored, otherwise will raise <tt class="docutils literal"><span class="pre"><span class="Identifier">OSError</span></span></tt>.</p>
