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