DESCRIPTION

52       memcached_pool() is used to create a connection pool of objects you may
53       use to remove the overhead of using  memcached_clone  for  short  lived
54       memcached_st objects. Please see libmemcached_configuration for details
55       on the format of the configuration string.
56
57       memcached_pool_destroy() is used to destroy the connection pool created
58       with  memcached_pool_create()  and  release all allocated resources. It
59       will return the pointer to the  memcached_st  structure  passed  as  an
60       argument  to  memcached_pool_create(), and returns the ownership of the
61       pointer to the caller when created with memcached_pool_create(), other‐
62       wise NULL is returned..
63
64       memcached_pool_fetch() is used to fetch a connection structure from the
65       connection pool. The relative_time argument specifies if  the  function
66       should  block and wait for a connection structure to be available if we
67       try to exceed the maximum size. You need to specify  time  in  relative
68       time.
69
70       memcached_pool_release()  is used to return a connection structure back
71       to the pool.
72
73       memcached_pool_behavior_get() and memcached_pool_behavior_set() is used
74       to get/set behavior flags on all connections in the pool.
75
76       Both  memcached_pool_release()  and  memcached_pool_fetch()  are thread
77       safe.
78

RETURN

80       memcached_pool_destroy() returns the pointer  (and  ownership)  to  the
81       memcached_st  structure  used to create the pool. If connections are in
82       use it returns NULL.
83
84       memcached_pool_pop() returns a pointer to a memcached_st structure from
85       the pool (or NULL if an allocation cannot be satisfied).
86
87       memcached_pool_release() returns MEMCACHED_SUCCESS upon success.
88
89       memcached_pool_behavior_get() and memcached_pool_behavior_get() returns
90       MEMCACHED_SUCCESS upon success.
91
92       If any methods returns MEMCACHED_IN_PROGRESS then a lock  on  the  pool
93       could  not be obtained. If any of the parameters passed to any of these
94       functions is invalid, MEMCACHED_INVALID_ARGUMENTS will be returned.
95
96       memcached_pool_fetch may return MEMCACHED_TIMEOUT if a  timeout  occurs
97       while  waiting  for  a free memcached_st. MEMCACHED_NOTFOUND if no mem‐
98       cached_st was available.
