9 C Client Library for memcached (libmemcached, -lmemcached)

15 memcached_delete (memcached_st *ptr,
16 const char *key, size_t key_length,
17 time_t expiration);

20 memcached_delete_by_key (memcached_st *ptr,

22 const char *key, size_t key_length,
23 time_t expiration);

26 memcached_delete() is used to delete a particular key.
27 memcached_delete_by_key() works the same, but it takes a master key to
28 find the given value.
29
30 Expiration works by placing the item into a delete queue, which means
31 that it won't possible to retrieve it by the "get" command, but "add"
32 and "replace" command with this key will also fail (the "set" command
33 will succeed, however). After the time passes, the item is finally
34 deleted from server memory.
35
36 Please note the the Danga memcached server removed support for
37 expiration in the 1.4 version.
38
40 A value of type "memcached_return_t" is returned On success that value
41 will be "MEMCACHED_SUCCESS". Use memcached_strerror() to translate
42 this value to a printable string.
43
44 If you are using the non-blocking mode of the library, success only
45 means that the message was queued for delivery.
