Function Documentation

graph_segment_list_get()

void graph_segment_list_get	(	capture_file *	cf,
		struct tcp_graph *	tg
	)

Fill in the segment list for a TCP graph

Parameters

cf	Capture file to scan
tg	TCP graph. A valid stream must be set. If either the source or destination address types are AT_NONE the address and port information will be filled in using the first packet in the specified stream.

rtt_is_retrans()

bool rtt_is_retrans	(	struct rtt_unack *	list,
		unsigned int	seqno
	)

Check if a sequence number is currently in the Unacked list, typically for avoiding adding redundant sequences. In practice, the retrans meaning in this particular code is different from TCP's one and would rather cover Keep-Alives and Spurious Retrans.

Parameters

list	The list containing the Unacked sequences
seqno	The sequence number to be searched for in the Unacked list

Returns

true if the list contains the sequence number, false otherwise
