should_connect_tunnel_to()

int should_connect_tunnel_to	(	size_t	count,
		size_t	src,
		size_t	dst
	)

Returns GNUNET_YES or GNUNET_NO to determine if the peer at index src should or should not connect outgoing to the peer at index dst to construct a complete basement with a given count of peers.

Parameters

[in]	count	Count of peers
[in]	src	Source index
[in]	dst	Destination index

Returns

GNUNET_YES or GNUNET_NO based on topologic requirement

required_connection_between()

int required_connection_between	(	size_t	count,
		size_t	src,
		size_t	dst
	)

Returns GNUNET_YES or GNUNET_NO to determine if the peers of index src and index dst should be connected in any direction to construct a complete basement with a given count of peers.

Parameters

[in]	count	Count of peers
[in]	src	Source index
[in]	dst	Destination index

Returns

GNUNET_YES or GNUNET_NO based on topologic requirement
