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. + + +---- +HOME +---- + + +To find out more information please check: +`http://libmemcached.org/ <http://libmemcached.org/>`_ + + +------ +AUTHOR +------ + + +Brian Aker, <brian@tangent.org> + +Trond Norbye, <trond.norbye@gmail.com> + + +-------- +SEE ALSO +-------- + +:manpage:`memcached(1)` :manpage:`libmemcached(3)` :manpage:`memcached_strerror(3)` :manpage:`libmemcached_configuration(3)` |
