+DESCRIPTION
+-----------
+
+
+:c:func:`memcached_pool` is used to create a connection pool of objects you
+may use to remove the overhead of using memcached_clone for short lived
+:c:type:`memcached_st` objects. Please see :doc:`libmemcached_configuration` for details on the format of the configuration string.
+
+:c:func:`memcached_pool_destroy` is used to destroy the connection pool
+created with :c:func:`memcached_pool_create` and release all allocated
+resources. It will return the pointer to the :c:type:`memcached_st` structure
+passed as an argument to :c:func:`memcached_pool_create`, and returns the ownership of the pointer to the caller when created with :c:func:`memcached_pool_create`, otherwise NULL is returned..
+
+:c:func:`memcached_pool_fetch` is used to fetch a connection structure from the
+connection pool. The relative_time argument specifies if the function should
+block and wait for a connection structure to be available if we try
+to exceed the maximum size. You need to specify time in relative time.
+
+:c:func:`memcached_pool_release` is used to return a connection structure back to the pool.
+
+:c:func:`memcached_pool_behavior_get` and :c:func:`memcached_pool_behavior_set` is used to get/set behavior flags on all connections in the pool.
+
+Both :c:func:`memcached_pool_release` and :c:func:`memcached_pool_fetch` are thread safe.
+
+------
+RETURN
+------
+
+:c:func:`memcached_pool_destroy` returns the pointer (and ownership) to the :c:type:`memcached_st` structure used to create the pool. If connections are in use it returns NULL.
+
+:c:func:`memcached_pool_pop` returns a pointer to a :c:type:`memcached_st` structure from the pool (or NULL if an allocation cannot be satisfied).
+
+:c:func:`memcached_pool_release` returns :c:type:`MEMCACHED_SUCCESS` upon success.
+
+:c:func:`memcached_pool_behavior_get` and :c:func:`memcached_pool_behavior_get` returns :c:type:`MEMCACHED_SUCCESS` upon success.
+
+If any methods returns MEMCACHED_IN_PROGRESS then a lock on the pool could not be obtained. If any of the parameters passed to any of these functions is invalid, MEMCACHED_INVALID_ARGUMENTS will be returned.
+
+memcached_pool_fetch may return MEMCACHED_TIMEOUT if a timeout occurs while waiting for a free memcached_st. MEMCACHED_NOTFOUND if no memcached_st was available.
