DESCRIPTION
-----------
-: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.

+RETURN VALUE
+------------
+
+:func:`memcached_fetch` sets error to
to `MEMCACHED_END` upon successful conclusion.
+
`MEMCACHED_NOTFOUND` will be return if no keys at all were found.
`MEMCACHED_KEY_TOO_BIG` is set to error whenever :func:`memcached_fetch` was used
and the key was set larger then `MEMCACHED_MAX_KEY`, which was the largest
key allowed for the original memcached ascii server.
