memcached_fetch() is used to fetch an individual value from the server. memcached_mget() must always be called before using this method.
-You must pass in a key and its length to fetch the object. You must supply
-three pointer variables which will give you the state of the returned
-object. A uint32_t pointer to contain whatever flags you stored with the value, a size_t pointer which will be filled with size of of the
-object, and a memcached_return_t pointer to hold any error. The
-object will be returned upon success and NULL will be returned on failure. MEMCACHED_END is returned by the *error value when all objects that have been found are returned. The final value upon MEMCACHED_END is null.
Values returned by memcached_fetch() must be freed by the caller.

-functions with this behavior on will result in MEMCACHED_NOT_SUPPORTED being returned, or for those functions which do not return a memcached_return_t, the error function parameter will be set to MEMCACHED_NOT_SUPPORTED.
