NAME
       memcached_delete_by_key - libmemcached Documentation

SYNOPSIS
       #include <libmemcached/memcached.h>
              Compile and link with -lmemcached

       memcached_return_t memcached_delete(memcached_st *ptr, const char *key,
       size_t key_length, time_t expiration)

       memcached_return_t  memcached_delete_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

                     o ptr -- pointer to initialized memcached_st struct

                     o group_key -- key namespace

                     o group_key_length -- length of the group_key without any
                       terminating zero

                     o key -- the key to delete

                     o key_length  -- the length og the key without any termi-
                       nating zero

                     o expiration -- obsolete since memcached(1) version 1.4

              Returns
                     memcached_return_t indicating success

DESCRIPTION
       memcached_delete()   is   used   to   delete    a    particular    key.
       memcached_delete_by_key()  works the same, but it takes a master key to
       find the given value.

       Expiration works by placing the item into a delete queue,  which  means
       that  it  won't  be  possible  to retrieve it by the "get" command. The
       "add" and "replace" commands with this key will also  fail  (the  "set"
       command will succeed, however).  After the time passes, the item is fi-
       nally deleted from server memory.

       Please note the the memcached server removed tests  for  expiration  in
       the 1.4 version.

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.

       If  you  are  using  the non-blocking mode of the library, success only
       means that the message was queued for delivery.
