memcached_get() is used to fetch an individual value from the server.
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
+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. Any
object returned by memcached_get() must be released by the caller
application.
memcached_mget() is used to select multiple keys at once. For
-multiple key operations it is always faster to use this function. This function always works asynchronously.
To retrieve data after a successful execution of memcached_mget(), you will need to
-call memcached_fetch_result(). You should continue to call this function until
-it returns a NULL (i.e. no more values). If you need to quit in the middle of a
-memcached_mget() call, you can execute a memcached_quit(), those this is not required.
memcached_fetch_result() is used to fetch an individual value from the server. memcached_mget() must always be called before using this method.

a memory reference you supply the calling function. Currently only one value
is being passed to each function call. In the future there will be an option
to allow this to be an array.
