The + module contains system calls to manipulate POSIX message queues. It also + contains a file system to implement a view for all message queues of the + system. This helps users to keep track of their message queues and make it + more easily usable without having to invent additional tools.</p> +<p class="Pp">The most common usage is as follows:</p> +<p class="Pp"></p> +<div class="Bd Bd-indent"><code class="Li">mount -t mqueuefs null + /mnt/mqueue</code></div> +<p class="Pp">where <span class="Pa">/mnt/mqueue</span> is a mount point.</p> +<p class="Pp">It is possible to define an entry in + <span class="Pa">/etc/fstab</span> that looks similar to:</p> +<div class="Bd Pp Li"> +<pre>null /mnt/mqueue mqueuefs rw 0 0</pre> +</div> +<p class="Pp">This will mount <code class="Nm">mqueuefs</code> at the + <span class="Pa">/mnt/mqueue</span> mount point during system boot. Using + <span class="Pa">/mnt/mqueue</span> as a permanent mount point is not + advised as its intention has always been to be a temporary mount point. See + <a class="Xr">hier(7)</a> for more information on + <span class="Ux">FreeBSD</span> directory layout.</p> +<p class="Pp">Some common tools can be used on the file system, e.g.: + <a class="Xr">cat(1)</a>, <a class="Xr">chmod(1)</a>, + <a class="Xr">chown(8)</a>, <a class="Xr">ls(1)</a>, + <a class="Xr">rm(1)</a>, etc. To use only the message queue system calls, it + is not necessary for user to mount the file system, just load the module or + compile it into the kernel. Manually creating a file, for example, + “<code class="Li">touch /mnt/mqueue/myqueue</code>”, will + create a message queue named <span class="Pa">myqueue</span> in the kernel, + default message queue attributes will be applied to the queue.
