<h1> The <tt>s6-fdholder-setdumpc</tt> program </h1>
<p>
<tt>s6-fdholder-setdumpc</tt> talks to a
<a href="s6-fdholderd.html">fd-holding daemon</a> on its open
descriptors 6 and 7, and transmits it a set of file descriptors
together with a list of identifiers and expiration dates found
in its environment.
</p>
<h2> Interface </h2>
<pre>
s6-fdholder-setdumpc [ -t <em>timeout</em> ]
</pre>
<ul>
<li> s6-fdholder-storec expects to talk to a listening
<a href="s6-fdholderd.html">s6-fdholderd</a> program on its descriptors 6 and 7. </li>
<li> It attempts to pass a complete state - i.e. a set of file descriptors
with identifiers and expiration dates - to s6-fdholderd. </li>
<li> It then exits 0, or 1 if the server returned an error. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-t <em>timeout</em></tt> : if the operation cannot be
processed in <em>timeout</em> milliseconds, then fail with an error message.
Communications with the server should be near-instant, so this option is
only here to protect users against programming errors. </li>
</ul>
<h2> Notes </h2>
<ul>
<li> The error messages for the s6-fdholder suite are explained
<a href="s6-fdholder-errorcodes.html">here</a>. </li>
<li> The format of the environment variables where s6-fdholder-setdumpc
gets its information from is the same as the one set by
<a href="s6-fdholder-getdumpc.html">s6-fdholder-getdumpc</a>. </li>
</ul>
