Functions
void	tsync_init (void)
	Initializes the time synchronization.
void	tsync_close (void)
	Cleanup at shutdown time.
void	tsync_send (struct gnutella_node *n, guint32 node_id)
	Send time synchronization request to specified node.
void	tsync_send_timestamp (tm_t *orig, tm_t *final)
	Called when final "T1" timestamp was written to the request, which superseded the original timestamp we had.
void	tsync_got_request (struct gnutella_node *n, tm_t *got)

Function Documentation

void tsync_close (  void   )

Cleanup at shutdown time.

void tsync_got_reply (  struct gnutella_node *  n, tm_t *  sent, tm_t *  received, tm_t *  replied, tm_t *  got, gboolean  ntp )

Got a reply to our initial "Time Sync" request.

void tsync_got_request (  struct gnutella_node *  n, tm_t *  got )

Got time request, answer it. Parameters: n  is the node from which we got the request got  is the timestamp at which we received the request

void tsync_init (  void   )

Initializes the time synchronization.

void tsync_send (  struct gnutella_node *  n, guint32  node_id )

Send time synchronization request to specified node. When node_id is non-zero, it refers to the connected node to which we're sending the time synchronization request.

void tsync_send_timestamp (  tm_t *  orig, tm_t *  final )

Called when final "T1" timestamp was written to the request, which superseded the original timestamp we had. Note that this routine will be called each time the message is scheduled for writing, which does not mean it will get written, especially when enqueued in a TCP message queue with lower stages flow-controlling...
