Detailed Description

Note that we do not store the actual source IP address in the context because the address is already be set in the network interface struct. If there is no such source address there, the packet cannot be sent anyway. This saves 12 bytes / context in IPv6.

Field Documentation

union { ... } net_context::@163

IPv6 hop limit or IPv4 ttl for packets sent via this context.

conn_handler

struct net_conn_handle* net_context::conn_handler

Connection handle

connect_cb

net_context_connect_cb_t net_context::connect_cb

Connect callback to be called when a connection has been established.

flags

uint16_t net_context::flags

Flags for the context

iface

int8_t net_context::iface

Network interface assigned to this context

ipv4_ttl

uint8_t net_context::ipv4_ttl

ipv6_hop_limit

uint8_t net_context::ipv6_hop_limit

local

struct sockaddr_ptr net_context::local

Local endpoint address. Note that the values are in network byte order.

lock

struct k_mutex net_context::lock

Internal lock for protecting this context from multiple access.

struct { ... } net_context::options

Option values

proto

uint16_t net_context::proto

Protocol (UDP, TCP or IEEE 802.3 protocol value)

recv_cb

net_context_recv_cb_t net_context::recv_cb

Receive callback to be called when desired packet has been received.

refcount

atomic_t net_context::refcount

Reference count

remote

struct sockaddr net_context::remote

Remote endpoint address. Note that the values are in network byte order.

send_cb

net_context_send_cb_t net_context::send_cb

Send callback to be called when the packet has been sent successfully.

user_data

void* net_context::user_data

User data.

First member of the structure to let users either have user data associated with a context, or put contexts into a FIFO.
