NAME¶
memcached_touch_by_key - libmemcached Documentation
SYNOPSIS¶
- #include <libmemcached/memcached.h>
- Compile and link with -lmemcached
- ptr -- pointer to initialized memcached_st struct
- key -- the key to touch
- key_length -- the length of key without any terminating zero
- expiration -- new expiration as a unix timestamp or as relative expiration time in seconds
- Returns
- memcached_return_t indicating success
- ptr -- pointer to initialized memcached_st struct
- group_key -- the key namespace
- group_key_length -- the length of group_key without any terminating zero
- key -- the key to touch
- key_length -- the length of key without any terminating zero
- expiration -- new expiration as a unix timestamp or as relative expiration time in seconds

- memcached_return_t indicating success
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.
