   5 #
   6 # Echo back a unique integer value
   7 #
   8 # This is used by clients talking to the guest agent over the
   9 # wire to ensure the stream is in sync and doesn't contain stale
  10 # data from previous client. All guest agent responses should be
  11 # ignored until the provided unique integer value is returned,
  12 # and it is up to the client to handle stale whole or
  13 # partially-delivered JSON text in such a way that this response
  14 # can be obtained.
  15 #
  16 # Such clients should also preceed this command
  17 # with a 0xFF byte to make such the guest agent flushes any
  18 # partially read JSON data from a previous session.
  19 #
  20 # @id: randomly generated 64-bit integer
  21 #
  22 # Returns: The unique integer id passed in by the client
