-The above code would create a connection and then free the connection when
-finished.
+In the above code you create a \ ``memcached_st``\ object with three server by making use of :manpage:`memcached_create_with_options(3)`.

+Creating a pool of servers

.. code-block:: c

- memcached_st *memc= memcached_create(NULL);
- char servername[]= "0.example.com";
-
- servers= memcached_server_list_append(NULL, servername, 400, &rc);
-
- for (x= 0; x < 20; x++)
- {
- char buffer[SMALL_STRING_LEN];
-
- snprintf(buffer, SMALL_STRING_LEN, "%u.example.com", 400+x);
- servers= memcached_server_list_append(servers, buffer, 401, &rc);
- }
- rc= memcached_server_push(memc, servers);
- memcached_server_free(servers);
- memcached_free(memc);
+ const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com";
+
+ memcached_pool_st* pool= memcached_pool(config_string, strlen(config_string));
+
+ memcached_return_t rc;
+
+ memcached_st *memc= memcached_pool_pop(pool, false, &rc);
+
+ .... do work
+
+ /*
+ Release the memc_ptr that was pulled from the pool
+ */
+ memcached_pool_push(pool, memc);
+
+ /*
+ Destroy the pool.
+ */
+ memcached_pool_destroy(pool);
+
-In the above code you create a \ ``memcached_st``\ object that you then feed in a
-single host into. In the for loop you build a \ ``memcached_server_st``\
-pointer that you then later feed via memcached_server_push() into the
-\ ``memcached_st``\ structure.
+In the above code you create a \ ``memcached_pool_st``\ object with three
+server by making use of :manpage:`memcached_pool(3)`.
-You can reuse the \ ``memcached_server_st``\ object with multile \ ``memcached_st``\
-structures.
+When memcached_pool_destroy() all memory will be released that is associated
+with the pool.

- for (x= 0; x < value_length; x++)
- value[x] = (char) (x % 127);
-
- for (x= 0; x < 1; x++)
+ char *value= "value";
+
+ memcached_return_t rc= memcached_set(memc, key, strlen(key), value, value_length, (time_t)0, (uint32_t)0);

It is best practice to always look at the return value of any operation.
