memcached_return_t memcached_touch(memcached_st *ptr, const char *key, size_t key_length, time_t expiration)
memcached_return_t memcached_touch_by_key(memcached_st *ptr, const char *group_key, size_t group_key_length, const char *key, size_t key_length, time_t expiration)
Compile and link with -lmemcached
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.
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.
