DESCRIPTION
-----------
-:c:func:`memcached_fetch()` is used to fetch an individual value from the server. :c:func:`memcached_mget()` must always be called before using this method.
+:c:func:`memcached_fetch` is used to fetch an individual value from the server. :c: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 :c:type:`uint32_t` pointer to contain whatever flags you stored with the value, a :c:type:`size_t` pointer which will be filled with size of of the
object, and a :c:type:`memcached_return_t` pointer to hold any error. The
-object will be returned upon success and NULL will be returned on failure. :c:type:`MEMCACHD_END` is returned by the \*error value when all objects that have been found are returned. The final value upon :c:type:`MEMCACHED_END` is null.
