-In the above code you create a \fBmemcached_st\fP object that you then feed in a
-single host into. In the for loop you build a \fBmemcached_server_st\fPpointer that you then later feed via memcached_server_push() into the
-\fBmemcached_st\fP structure.
+In the above code you create a \fBmemcached_pool_st\fP object with three
+server by making use of \fBmemcached_pool()\fP.
.sp
-You can reuse the \fBmemcached_server_st\fP object with multile \fBmemcached_st\fPstructures.
+When \fBmemcached_pool_destroy()\fP all memory will be released that is associated
+with the pool.
