NAME
memcached_touch_by_key - libmemcached Documentation
SYNOPSIS
#include <libmemcached/memcached.h>
Compile and link with -lmemcached
memcached_return_t memcached_touch(memcached_st *ptr, const char *key, size_t key_length, time_t
expiration)
Parameters
• 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
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)
Parameters
• 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
Returns
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.
