<h1> The <tt>skabus-dyntee-client</tt> program </h1>
<p>
<tt>skabus-dyntee-client</tt> is a client for the
<a href="skabus-dyntee.html">skabus-dyntee</a> server.
It connects to a Unix domain socket where a
<a href="skabus-dyntee.html">skabus-dyntee</a> instance is listening,
then executes into a program with the data stream from skabus-dyntee
on its standard input.
</p>
<h2> Interface </h2>
<pre>
skabus-dyntee-client <em>path</em> <em>prog...</em>
</pre>
<ul>
<li> skabus-dyntee-client connects to the Unix domain socket at <em>path</em>.
It assumes the other end of the socket is a <a href="skabus-dyntee.html">skabus-dyntee</a>
(or <a href="skabus-dynteed.html">skabus-dynteed</a>, which is the same) instance. </li>
<li> It executes into the <em>prog...</em> command line with the
socket as <em>prog</em>'s standard input. </li>
</ul>
<h2> Notes </h2>
<ul>
<li> It is possible for <em>prog</em> to immediately get EOF on its
standard input. This likely means that the server has denied the
connection (skabus-dyntee-client did not run with an authorized uid
or gid). But it could also mean that the stream ended right after
the client connected. </li>
<li> The socket is shut down for writing, so <em>prog</em> can
only read on its stdin; attempts to write will always fail. </li>
</ul>
