46                       zero
47
48                     • expiration -- new expiration as a unix timestamp or  as
49                       relative expiration time in seconds

52                     memcached_return_t indicating success
53

DESCRIPTION

55       memcached_touch()  is used to update the expiration time on an existing
56       key.  memcached_touch_by_key() works the same, but it  takes  a  master
57       key to find the given value.
58

RETURN VALUE

60       A  value of type memcached_return_t is returned.  On success that value
61       will be MEMCACHED_SUCCESS.  Use memcached_strerror() to translate  this
62       value to a printable string.
