  33 DESCRIPTION
  34 -----------
  35
  36
  37 :c:func:`memcached_pool()` is used to create a connection pool of objects you
  38 may use to remove the overhead of using memcached_clone for short lived
  39 :c:type:`memcached_st` objects. Please see :doc:`libmemcached_configuration` for details on the format of the configuration string.
  40
  41 :c:func:`memcached_pool_destroy()` is used to destroy the connection pool
  42 created with :c:func:`memcached_pool_create()` and release all allocated
  43 resources. It will return the pointer to the :c:type:`memcached_st` structure
  44 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..
  45
  46 :c:func:`memcached_pool_pop()` is used to grab a connection structure from the
  47 connection pool. The block argument specifies if the function should
  48 block and wait for a connection structure to be available if we try
  49 to exceed the maximum size.
  50
  51 :c:func:`memcached_pool_push()` is used to return a connection structure back to the pool.
  52
  53 :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.
  54

  56 ------
  57 RETURN
  58 ------
  59
  60 :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.
  61
  62 :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).
  63
  64 :c:func:`memcached_pool_push()` returns :c:type:`MEMCACHED_SUCCESS` upon success.
  65
  66 :c:func:`memcached_pool_behavior_get()` and :c:func:`memcached_pool_behavior_get()` returns :c:type:`MEMCACHED_SUCCESS` upon success.
