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.
