Function Documentation

net_recv_data()

int net_recv_data	(	struct net_if *	iface,
		struct net_pkt *	pkt
	)

#include <include/zephyr/net/net_core.h>

Called by lower network stack or network device driver when a network packet has been received.

The function will push the packet up in the network stack for further processing.

Parameters

iface	Network interface where the packet was received.
pkt	Network packet data.

Returns

0 if ok, <0 if error.

net_send_data()

int net_send_data

(

struct net_pkt *

pkt

)

#include <include/zephyr/net/net_core.h>

Send data to network.

Send data to network. This should not be used normally by applications as it requires that the network packet is properly constructed.

Parameters

pkt	Network packet.

Returns

0 if ok, <0 if error. If <0 is returned, then the caller needs to unref the pkt in order to avoid memory leak.
