DESCRIPTION

21       memcached_delete()   is   used   to   delete    a    particular    key.
22       memcached_delete_by_key()  works the same, but it takes a master key to
23       find the given value.
24
25       Expiration works by placing the item into a delete queue,  which  means
26       that  it  won't  be  possible  to retrieve it by the "get" command. The
27       "add" and "replace" commands with this key will also  fail  (the  "set"
28       command  will  succeed,  however).  After  the time passes, the item is
29       finally deleted from server memory.
30
31       Please note the the Danga memcached server removed tests for expiration
32       in the 1.4 version.

RETURN

35       A  value  of  type memcached_return_t is returned On success that value
36       will be MEMCACHED_SUCCESS.  Use memcached_strerror() to translate  this
37       value to a printable string.
38
39       If  you  are  using  the non-blocking mode of the library, success only
40       means that the message was queued for delivery.
