<h3>Sommaire</h3>

    <p><code class="module"><a href="../mod/mod_slotmem_plain.html">mod_slotmem_plain</a></code> est un fournisseur de m&eacute;moire qui
    permet la cr&eacute;ation et l'utilisation d'un segment de m&eacute;moire contigu
    dans lequel les ensembles de donn&eacute;es sont organis&eacute;s en "slots".
    </p>

    <p>Si la m&eacute;moire doit &ecirc;tre partag&eacute;e entre des threads et des
    processus, il est pr&eacute;f&eacute;rable d'utiliser le fournisseur
    <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> fournit une API comprenant les
    fonctions suivantes :
    </p>
