DESCRIPTION

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

RETURN VALUE

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