DESCRIPTION

       memcached_pool_create() 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. The
       mmc argument should be an initialised "memcached_st" structure, and a successfull
       invocation of memcached_pool_create takes full ownership of the variable (until it is
       released by memcached_pool_destroy). The "initial" argument specifies the initial size of
       the connection pool, and the "max" argument specifies the maximum size the connection pool
       should grow to. Please note that the library will allocate a fixed size buffer scaled to
       the max size of the connection pool, so you should not pass MAXINT or some other large
       number here.

       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.

       memcached_pool_pop() is used to grab a connection structure from the connection pool. The
       block argument specifies if the function should block and wait for a connection structure
       to be available if we try to exceed the maximum size.

       memcached_pool_push() is used to return a connection structure back to the pool.

       memcached_pool_behavior_set() and memcached_pool_behagior_get() is used to get/set
       behavior flags on all connections in the pool.

RETURN

       memcached_pool_create() returns a pointer to the newly created memcached_pool_st
       structure. On an allocation failure, it returns NULL.

       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_push() returns MEMCACHED_SUCCESS upon success.

       memcached_pool_behavior_get() and memcached_pool_behavior_get() returns MEMCACHED_SUCCESS
       upon success.
