<p>sockrecv —
Receives data from other processes using the low-level UDP or TCP protocols
</p>
</div>
<div class="refsect1" title="Description">
<a id="idp44216208"></a>
<h2>Description</h2>
<p>
Receives directly using the UDP (<span class="emphasis"><em>sockrecv</em></span> and
<span class="emphasis"><em>sockrecvs</em></span>) or TCP (<span class="emphasis"><em>strecv</em></span>)
protocol onto a network. The data is not subject to any encoding or special
routing. The <span class="emphasis"><em>sockrecvs</em></span> opcode receives a stereo signal
interleaved.

<div class="refsect1" title="Initialization">
<a id="idp44254448"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>Sipaddr</em></span>
-- a string that is the IP address of the sender in standard
4-octet dotted form.
</p>
<p>
<span class="emphasis"><em>iport</em></span>
-- the number of the port that is used for the communication.
</p>
<p>
<span class="emphasis"><em>ilength</em></span>
-- the length of the individual packets in UDP transmission.
This number must be sufficiently small to fit a single MTU,
which is set to the save value of 1456. In UDP transmissions
the sender and receiver needs agree on this value
