<h3>dp_recv</h3>
<p><strong>Syntax</strong></p>
<pre>dp_recv <em>chanId</em></pre>
<p><strong>Comments</strong></p>
<p>dp_recv allows one to bypass the Tcl I/O layer and call the
channel's receive method directly. There are several problems
with Tcl's I/O system because it buffers data internally and it
is line or file-based.</p>
<p>dp_recv calls the channel's receive method <strong>once</strong>
and returns the received data.</p>
<p><strong>Examples</strong></p>
<pre>set a [dp_recv $chan]</pre>
