<h1> The <tt>s6-fdholder-transferdump</tt> program </h1>
<p>
<tt>s6-fdholder-transferdump</tt> connects to two separate
<a href="s6-fdholderd.html">fd-holding daemons</a> and
transfers the content of the first one to the second one.
</p>
<h2> Interface </h2>
<pre>
s6-fdholder-transferdump [ -t <em>timeoutfrom:timeoutto</em> ] <em>pathfrom</em> <em>pathto</em>
</pre>
<ul>
<li> s6-fdholder-transferdump executes into a more complex command line
involving two
<a href="s6-ipcclient.html">s6-ipcclient</a> invocations and ending with
<a href="s6-fdholder-transferdumpc.html">s6-fdholder-transferdumpc</a>. It
is just a convenience program: the real transfer is performed by
<a href="s6-fdholder-transferdumpc.html">s6-fdholder-transferdumpc</a>. </li>
<li> The file descriptor transfer will occur from the
<a href="s6-fdholderd.html">s6-fdholderd</a> daemon listening on
<em>pathfrom</em> to the one listening on <em>pathto</em>. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-t <em>timeoutfrom</em>:<em>timeoutto</em></tt> :
if the operations cannot be
processed in <em>timeoutfrom</em> (for the connection to <em>pathfrom</em>)
or <em>timeoutto</em> (for the connection to <em>pathto</em>) milliseconds,
then fail with an error message.
Communications with the servers should be near-instant, so this option is
only here to protect users against programming errors (connecting to the
wrong socket, for instance). </li>
</ul>
