DESCRIPTION

       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
       memcached_st objects. Please see libmemcached_configuration for details
       on the format of the configuration string.

       memcached_pool_destroy() is used to destroy the connection pool created
       with  memcached_pool_create()  and  release all allocated resources. It
       will return the pointer to the  memcached_st  structure  passed  as  an
       argument  to  memcached_pool_create(), and returns the ownership of the
       pointer  to  the  caller  when  created  with  memcached_pool_create(),
       otherwise NULL is returned..

       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.

       memcached_pool_release()  is used to return a connection structure back
       to the pool.

       memcached_pool_behavior_get() and memcached_pool_behavior_set() is used
       to get/set behavior flags on all connections in the pool.

       Both  memcached_pool_release()  and  memcached_pool_fetch()  are thread
       safe.

RETURN

       memcached_pool_destroy() returns the pointer  (and  ownership)  to  the
       memcached_st  structure  used to create the pool. If connections are in
       use it returns NULL.

       memcached_pool_pop() returns a pointer to a memcached_st structure from
       the pool (or NULL if an allocation cannot be satisfied).

       memcached_pool_release() returns MEMCACHED_SUCCESS upon success.

       memcached_pool_behavior_get() and memcached_pool_behavior_get() returns
       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.
