+:func:`memcached_fetch` is used to fetch an individual value from the server. :func:`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 :type:`uint32_t` pointer to contain whatever flags you stored with the value, a :type:`size_t` pointer which will be filled with size of of the
object, and a :type:`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 :func:`memcached_fetch` must be freed by the caller.

`MEMCACHED_BEHAVIOR_USE_UDP` has been set. Executing any of these
functions with this behavior on will result in `MEMCACHED_NOT_SUPPORTED` being returned, or for those functions which do not return a :type:`memcached_return_t`, the error function parameter will be set to `MEMCACHED_NOT_SUPPORTED`.
