<h3>Sommaire</h3>
<p><code class="module"><a href="../mod/mod_slotmem_plain.html">mod_slotmem_plain</a></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 class="module"><a href="../mod/mod_slotmem_plain.html">mod_slotmem_plain</a></code> fournit une API comprenant les
fonctions suivantes :
</p>
<pre class="prettyprint lang-c">/* appelle le callback sur tous les slots actifs */
apr_status_t doall(ap_slotmem_instance_t *s, ap_slotmem_callback_fn_t *func, void *data, apr_pool_t *pool)
/* crée un nouveau slot de mémoire dont chaque item aura une taille de item_size. */
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)
/* rattache à un slot de mémoire existant. */
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)
/* indique la mémoire associée à ce slot actif. */
apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void **mem)
/* lit la mémoire depuis ce slot et la transfert vers dest */
apr_status_t get(ap_slotmem_instance_t *s, unsigned int item_id, unsigned char *dest, apr_size_t dest_len)
/* écrit dans ce slot la mémoire en provenance de src */
apr_status_t put(ap_slotmem_instance_t *slot, unsigned int item_id, unsigned char *src, apr_size_t src_len)
/* renvoie le nombre total de slots contenus dans ce segment */
unsigned int num_slots(ap_slotmem_instance_t *s)
/* renvoie la taille totale des données, en octets, contenues dans un slot de ce segment */
apr_size_t slot_size(ap_slotmem_instance_t *s)
/* alloue le premier slot libre et le marque comme utilisé (n'effectue aucune copie de données) */
apr_status_t grab(ap_slotmem_instance_t *s, unsigned int *item_id)
/* appropriation ou allocation forcée du slot spécifié et marquage comme utilisé (n'effectue aucune copie de données) */
apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id)
/* libère un slot et le marque comme non utilisé (n'effectue aucune copie de données) */
apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id)</pre>
