<pre class="base-tree">
object --+

<strong class="uidshort">types.UnixFd</strong>
</pre>
<hr />
<p>An Unix Fd.</p>
<p>Constructor:</p>
<pre class="rst-literal-block">
dbus.UnixFd(value: int or file object[, variant_level: int]) -> UnixFd
</pre>
<p><tt class="rst-docutils literal">value</tt> must be the integer value of a file descriptor, or an object that
implements the fileno() method. Otherwise, <code class="link">ValueError</code> will be
raised.</p>
<p>UnixFd keeps a dup() (duplicate) of the supplied file descriptor. The
caller remains responsible for closing the original fd.</p>
<p><tt class="rst-docutils literal">variant_level</tt> must be non-negative; the default is 0.</p>
