<h3>Sommaire</h3>

    <p><code>mod_slotmem_plain</code> est un fournisseur de mémoire qui
    permet la création et l'utilisation d'un segment de mémoire contigu
    dans lequel les ensembles de données sont organisés en "slots".
    </p>

    <p>Si la mémoire doit être partagée entre des threads et des
    processus, il est préférable d'utiliser le fournisseur
    <code class="module"><a href="../mod/mod_slotmem_shm.html">mod_slotmem_shm</a></code>.
    </p>

    <p><code>mod_slotmem_plain</code> fournit une API comprenant les
    fonctions suivantes :
    </p>

    <dl>
      <dt>apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)</dt>
      <dd>appelle le callback sur tous les slots actifs</dd>

      <dt>apr_status_t create(ap_slotmem_instance_t **new, const char *name, apr_size_t item_size, unsigned int item_num, ap_slotmem_type_t type, apr_pool_t *pool)</dt>
      <dd>crée un nouveau slot de mémoire dont chaque objet aura une
      taille de item_size.</dd>

      <dt>apr_status_t attach(ap_slotmem_instance_t **new, const char *name, apr_size_t *item_size, unsigned int *item_num, apr_pool_t *pool)</dt>
      <dd>rattache à un slot de mémoire existant.</dd>

      <dt>apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void**mem)</dt>
      <dd>indique la mémoire associée à ce slot actif.</dd>

      <dt>apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)</dt>
      <dd>lit la mémoire depuis ce slot et la transfère vers dest</dd>

      <dt>apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)</dt>
      <dd>écrit dans ce slot la mémoire en provenance de src</dd>

      <dt>unsigned int num_slots(ap_slotmem_instance_t *s)</dt>
      <dd>renvoie le nombre total de slots contenus dans ce segment</dd>

      <dt>apr_size_t slot_size(ap_slotmem_instance_t *s)</dt>
      <dd>renvoie la taille totale des données, en octets, contenues
      dans un slot de ce segment</dd>

      <dt>apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id);</dt>
      <dd>alloue le premier slot disponible et le marque comme utilisé (n'effectue aucune
      copie de données)</dd>

      <dt>apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id);</dt>
      <dd>force l'allocation ou l'appropriation du slot spécifié et le marque comme utilisé (n'effectue aucune
      copie de données)</dd>

      <dt>apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id);</dt>
      <dd>libère un slot et le marque comme non utilisé (n'effectue aucune
      copie de données)</dd>
    </dl>
