+<h3>Summary</h3>
+
+ <p><code class="module"><a href="../mod/mod_slotmem_plain.html">mod_slotmem_plain</a></code> is a memory provider which
+ provides for creation and access to a plain memory segment
+ in which the datasets are organized in "slots."
+ </p>
+
+ <p>If the memory needs to be shared between threads and
+ processes, a better provider would be
+ <code class="module"><a href="../mod/mod_slotmem_shm.html">mod_slotmem_shm</a></code>.
+ </p>
+
+ <p><code class="module"><a href="../mod/mod_slotmem_plain.html">mod_slotmem_plain</a></code> provides the following API functions:
+ </p>
+
