  24 =head1 DESCRIPTION
  25
  26 memcached_delete() is used to delete a particular key. An expiration value
  27 can be applied so that the key is deleted after that many seconds, but this
  28 will only work if you are using a 1.2.x server. If you are using a 1.2.x
  29 server and you want to use the expiration value, please call memcached_version
  30 one time for the memcached_st instance. If you don't do this no-reply and
  31 buffered mode will be disabled to avoid getting out of sync with the server.
  32 memcached_delete_by_key() works the same, but it takes a master key to
  33 find the given value.
  34
  35 =head1 RETURN
  36
  37 A value of type C<memcached_return_t> is returned
  38 On success that value will be C<MEMCACHED_SUCCESS>.
  39 Use memcached_strerror() to translate this value to a printable string.
  40
  41 If you are using the non-blocking mode of the library, success only
  42 means that the message was queued for delivery.
