Function Documentation

mptcpd_lm_close()

MPTCPD_API int mptcpd_lm_close	(	struct mptcpd_lm *	lm,
		struct sockaddr const *	sa
	)

Stop listening on a MPTCP local address.

Parameters

[in]	lm	The mptcpd address listener manager object.
[in]	sa	The MPTCP local address with a non-zero port, such as the one assigned by mptcpd_lm_listen(), i.e. the non-zero port provided by the user or the ephemeral port chosen by the kernel.

Returns

0 if operation was successful. -1 or errno otherwise.

mptcpd_lm_listen()

MPTCPD_API int mptcpd_lm_listen	(	struct mptcpd_lm *	lm,
		struct sockaddr *	sa
	)

Listen on the given MPTCP local address.

Create a MPTCP listening socket for the given local address. This is needed to accept subflows, e.g. during a MP_JOIN operation.

Parameters

[in]	lm	The mptcpd address listener manager object.
[in,out]	sa	The MPTCP local address. If the port is zero an ephemeral port will be chosen, and assigned to the appropriate underlying address family-specific port member, e.g. sin_port or sin6_port. The port will be in network byte order.

Returns

0 if operation was successful. -1 or errno otherwise.
