25 :c:func:`memcached_touch` is used to update the expiration time on an existing key.
26 :c:func:`memcached_touch_by_key` works the same, but it takes a master key
27 to find the given value.
35 A value of type :c:type:`memcached_return_t` is returned
36 On success that value will be :c:type:`MEMCACHED_SUCCESS`.
37 Use :c:func:`memcached_strerror` to translate this value to a printable
