48 memcached_delete() is used to delete a particular key.
49 memcached_delete_by_key() works the same, but it takes a master key to
52 Expiration works by placing the item into a delete queue, which means that
53 it won\(aqt possible to retrieve it by the "get" command, but "add" and
54 "replace" command with this key will also fail (the "set" command will
55 succeed, however). After the time passes, the item is finally deleted from server memory.
57 Please note the the Danga memcached server removed tests for expiration in
61 A value of type \fBmemcached_return_t\fP is returned
62 On success that value will be \fBMEMCACHED_SUCCESS\fP.
63 Use memcached_strerror() to translate this value to a printable string.
65 If you are using the non\-blocking mode of the library, success only
66 means that the message was queued for delivery.
