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.
