#include <libmemcached/memcached.h>

Compile and link with -lmemcached

memcached_return_t <#_CPPv418memcached_return_t> memcached_touch(memcached_st <#_CPPv412memcached_st> *ptr, const char *key, size_t key_length, time_t expiration)

Parameters

• ptr -- pointer to initialized memcached_st <#_CPPv412memcached_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 <#_CPPv418memcached_return_t> indicating success

memcached_return_t <#_CPPv418memcached_return_t> memcached_touch_by_key(memcached_st <#_CPPv412memcached_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 <#_CPPv412memcached_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 <#_CPPv418memcached_return_t> indicating success

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 <#_CPPv418memcached_return_t> is returned. On success that value will be MEMCACHED_SUCCESS <#_CPPv4N18memcached_return_t17MEMCACHED_SUCCESSE>. Use memcached_strerror() <#_CPPv418memcached_strerrorP12memcached_st18memcached_return_t> to translate this value to a printable string.
