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
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.
