# @guest-sync-delimited:
#
# Echo back a unique integer value, and prepend to response a leading
# sentinel byte (0xFF) the client can check scan for.
#
# This is used by clients talking to the guest agent over the wire to
# ensure the stream is in sync and doesn't contain stale data from
# previous client.  It must be issued upon initial connection, and
# after any client-side timeouts (including timeouts on receiving a
# response to this command).
#
# After issuing this request, all guest agent responses should be
# ignored until the response containing the unique integer value the
# client passed in is returned.  Receival of the 0xFF sentinel byte
# must be handled as an indication that the client's
# lexer/tokenizer/parser state should be flushed/reset in preparation
# for reliably receiving the subsequent response.  As an optimization,
# clients may opt to ignore all data until a sentinel value is
# receiving to avoid unnecessary processing of stale data.
#
# Similarly, clients should also precede this *request* with a 0xFF
# byte to make sure the guest agent flushes any partially read JSON
# data from a previous client connection.

# Returns: The unique integer id passed in by the client

# @guest-sync:
#
# Echo back a unique integer value
#
# This is used by clients talking to the guest agent over the wire to
# ensure the stream is in sync and doesn't contain stale data from
# previous client.  All guest agent responses should be ignored until
# the provided unique integer value is returned, and it is up to the
# client to handle stale whole or partially-delivered JSON text in
# such a way that this response can be obtained.
#
# In cases where a partial stale response was previously received by
# the client, this cannot always be done reliably.  One particular
# scenario being if qemu-ga responses are fed character-by-character
# into a JSON parser.  In these situations, using guest-sync-delimited
# may be optimal.
#
# For clients that fetch responses line by line and convert them to
# JSON objects, guest-sync should be sufficient, but note that in
# cases where the channel is dirty some attempts at parsing the
# response may result in a parser error.

# Such clients should also precede this command with a 0xFF byte to
# make sure the guest agent flushes any partially read JSON data from
