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 func-
tion 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 mem-
cached_st was available.
