<h3>Sommaire</h3>
<p><code>mod_slotmem_plain</code> est un fournisseur de m�moire qui
permet la cr�ation et l'utilisation d'un segment de m�moire contigu
dans lequel les ensembles de donn�es sont organis�s en "slots".
</p>
<p>Si la m�moire doit �tre partag�e entre des threads et des
processus, il est pr�f�rable 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>cr�e un nouveau slot de m�moire dont chaque item 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 � un slot de m�moire existant.</dd>
<dt>apr_status_t dptr(ap_slotmem_instance_t *s, unsigned int item_id, void**mem)</dt>
<dd>indique la m�moire associ�e � 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 m�moire depuis ce slot et la transfert 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>�crit dans ce slot la m�moire 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 donn�es, 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 libre et le marque comme utilis� (n'effectue aucune
copie de donn�es)</dd>
<dt>apr_status_t fgrab(ap_slotmem_instance_t *s, unsigned int item_id);</dt>
<dd>appropriation ou allocation forc�e du slot sp�cifi� et marquage comme
utilis� (n'effectue aucune copie de donn�es)</dd>
<dt>apr_status_t release(ap_slotmem_instance_t *s, unsigned int item_id);</dt>
<dd>lib�re un slot et le marque comme non utilis� (n'effectue aucune
copie de donn�es)</dd>
