-<h1> The <tt>s6-fdholder-retrievec</tt> program </h1>
-
-<p>
-<tt>s6-fdholder-retrievec</tt> talks to a
-<a href="s6-fdholderd.html">fd-holding daemon</a> on its open
-descriptors 6 and 7, and retrieves a file descriptor from it,
-then executes a program.
-</p>
-
-<h2> Interface </h2>
-
-<pre>
- s6-fdholder-retrievec [ -D ] [ -t <em>timeout</em> ] <em>id</em> <em>prog...</em>
-</pre>
-
-<ul>
- <li> s6-fdholder-retrievec 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 retrieve a copy of the file descriptor that has been
-stored into that daemon under identifier <em>id</em>.
- <li> It then executes into <em>prog...</em>, with the retrieved
-file descriptor as standard input. </li>
-</ul>
-
-<h2> Options </h2>
-
-<ul>
- <li> <tt>-D</tt>&nbsp;: delete the file descriptor from the server's
-storage after retrieval. This option requires writing rights over the
-given identifier as well as reading rights: check the server's
-<a href="s6-fdholderd.html#configuration">configuration</a>. </li>
- <li> <tt>-t&nbsp;<em>timeout</em></tt>&nbsp;: 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>s6-fdholder-retrievec is the "internal" version of
-<a href="s6-fdholder-retrieve.html">s6-fdholder-retrieve</a>. It simply
-expects to be run as a UCSPI client, i.e. talking to the server
-over descriptors 6 and 7, instead of connecting to the server
-itself. </li>
- <li> The error messages for the s6-fdholder suite are explained
-<a href="s6-fdholder-errorcodes.html">here</a>. </li>
