MEMCACHED_TOUCH_BY_KEY(3)

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.
