-:cfunc:`memcached_cas()` overwrites data in the server as long as the "cas"
+:c:func:`memcached_cas()` overwrites data in the server as long as the "cas"
value is still the same in the server. You can get the cas value of a result
by calling :c:func:`memcached_result_cas()` on a memcached_result_st(3)
structure. At the point that this note was written cas is still buggy in memached. Turning on tests for it in libmemcached(3) is optional. Please see
