<h2 id="_addressing">ADDRESSING</h2>
<div class="sectionbody">
<div class="paragraph"><p>A ØMQ address string consists of two parts as follows:
<em>transport</em><tt>://</tt><em>endpoint</em>. The <em>transport</em> part specifies the underlying
transport protocol to use, and for the inter-process transport shall be set to
<tt>ipc</tt>. The meaning of the <em>endpoint</em> part for the inter-process transport is
defined below.</p></div>
<h3 id="_assigning_a_local_address_to_a_socket">Assigning a local address to a socket</h3><div style="clear:left"></div>
<div class="paragraph"><p>When assigning a local address to a <em>socket</em> using <em>zmq_bind()</em> with the <em>ipc</em>
transport, the <em>endpoint</em> shall be interpreted as an arbitrary string
identifying the <em>pathname</em> to create. The <em>pathname</em> must be unique within the
operating system namespace used by the <em>ipc</em> implementation, and must fulfill
any restrictions placed by the operating system on the format and length of a
<em>pathname</em>.</p></div>
<h3 id="_connecting_a_socket">Connecting a socket</h3><div style="clear:left"></div>
<div class="paragraph"><p>When connecting a <em>socket</em> to a peer address using <em>zmq_connect()</em> with the
<em>ipc</em> transport, the <em>endpoint</em> shall be interpreted as an arbitrary string
identifying the <em>pathname</em> to connect to. The <em>pathname</em> must have been
previously created within the operating system namespace by assigning it to a
<em>socket</em> with <em>zmq_bind()</em>.</p></div>
