Function Documentation

gnrc_icmpv6_error_dst_unr_send()

void gnrc_icmpv6_error_dst_unr_send	(	uint8_t	code,
		const gnrc_pktsnip_t *	orig_pkt )

Sends an ICMPv6 destination unreachable message for sending.

Precondition

orig_pkt contains a packet snip of type GNRC_NETTYPE_IPV6

Note

Won't send if source address of orig_pkt is unspecified or multicast

Parameters

[in]	code	The code for the message.
[in]	orig_pkt	The invoking packet.

gnrc_icmpv6_error_param_prob_send()

void gnrc_icmpv6_error_param_prob_send	(	uint8_t	code,
		void *	ptr,
		const gnrc_pktsnip_t *	orig_pkt )

Sends an ICMPv6 parameter problem message for sending.

Precondition

orig_pkt is in receive order.

orig_pkt contains a packet snip of type GNRC_NETTYPE_IPV6

Note

Won't send if source address of orig_pkt is unspecified or multicast

Parameters

[in]	code	The code for the message.
[in]	ptr	Pointer to the erroneous octet in orig_pkt.
[in]	orig_pkt	The invoking packet.

gnrc_icmpv6_error_pkt_too_big_send()

void gnrc_icmpv6_error_pkt_too_big_send	(	uint32_t	mtu,
		const gnrc_pktsnip_t *	orig_pkt )

Sends an ICMPv6 packet too big message for sending.

Precondition

orig_pkt contains a packet snip of type GNRC_NETTYPE_IPV6

Note

Won't send if source address of orig_pkt is unspecified or multicast

Parameters

[in]	mtu	The maximum transission unit of the next-hop link.
[in]	orig_pkt	The invoking packet.

gnrc_icmpv6_error_time_exc_send()

void gnrc_icmpv6_error_time_exc_send	(	uint8_t	code,
		const gnrc_pktsnip_t *	orig_pkt )

Sends an ICMPv6 time exceeded message for sending.

Precondition

orig_pkt contains a packet snip of type GNRC_NETTYPE_IPV6

Note

Won't send if source address of orig_pkt is unspecified or multicast

Parameters

[in]	code	The code for the message.
[in]	orig_pkt	The invoking packet.
