+memcached_fetch_execute() is a callback function for result sets. Instead
+of returning the results to you for processing, it passes each of the

+a memcached_st that can be cloned for use in called the cluster (it can not

+memcached_get_by_key() and memcached_mget_by_key() behave in a similar nature
+as memcached_get() and memcached_mget(). The difference is that they take
+a master key that is used for determining which server an object was stored

 All objects returned must be freed by the calling application.
