		char const *	fname
	)

Check for genl operation failure.

Check for generic netlink operation failure, and log associated error message.

Parameters

[in]	msg	Generic netlink message information.
[in]	fname	Name function from which the error check was initiated.

Returns

true if no error was found, and false otherwise.

		void *	user_data
	)

Generic error reporting callback.

Parameters

[in]	msg	Generic netlink message information.
[in]	user_data	Function name.

mptcpd_get_port_number()

uint16_t mptcpd_get_port_number

(

struct sockaddr const *

addr

)

Get TCP port number (host byte order).

Parameters

[in]

addr

Network address information.

Get TCP port suitably typed for use in MPTCP generic netlink API calls, or zero if no address was provided.

Returns
