<div class="paragraph"><p>The method of choice for IPC in our case is a unix socket because it has very\r
little overhead on both sides and is usually available without headaches in\r
most languages. In the default configuration file, the ipc-socket gets created\r
-in <tt>/tmp/i3-%u/ipc-socket.%p</tt> where <tt>%u</tt> is your UNIX username and <tt>%p</tt> is the\r
-PID of i3.</p></div>\r
+in <tt>/tmp/i3-%u.XXXXXX/ipc-socket.%p</tt> where <tt>%u</tt> is your UNIX username, <tt>%p</tt> is\r
+the PID of i3 and XXXXXX is a string of random characters from the portable\r
+filename character set (see mkdtemp(3)). You can get the socketpath from i3 by\r
+calling <tt>i3 --get-socketpath</tt>.</p></div>\r
