Detailed Description

Macro Definition Documentation

◆ ZSOCK_IPV6_ADD_MEMBERSHIP

#define ZSOCK_IPV6_ADD_MEMBERSHIP 20

#include <zephyr/net/socket.h>

Join IPv6 multicast group.

◆ ZSOCK_IPV6_ADDR_PREFERENCES

#define ZSOCK_IPV6_ADDR_PREFERENCES 72

#include <zephyr/net/socket.h>

RFC5014: Source address selection.

◆ ZSOCK_IPV6_DONTFRAG

#define ZSOCK_IPV6_DONTFRAG 62

#include <zephyr/net/socket.h>

Disable local IPv6 fragmentation for packets sent on this socket.

Takes an integer boolean (0 = allow fragmentation, non-zero = disable). When enabled, datagrams larger than the interface MTU are rejected locally with errno set to EMSGSIZE instead of being fragmented by the stack.

Valid for setsockopt() and getsockopt() at the NET_IPPROTO_IPV6 level.

◆ ZSOCK_IPV6_DROP_MEMBERSHIP

#define ZSOCK_IPV6_DROP_MEMBERSHIP 21

#include <zephyr/net/socket.h>

Leave IPv6 multicast group.

◆ ZSOCK_IPV6_HOPLIMIT

#define ZSOCK_IPV6_HOPLIMIT 52

#include <zephyr/net/socket.h>

Set or receive the hoplimit value for an outgoing packet.

◆ ZSOCK_IPV6_JOIN_GROUP

#define ZSOCK_IPV6_JOIN_GROUP ZSOCK_IPV6_ADD_MEMBERSHIP

#include <zephyr/net/socket.h>

Join IPv6 multicast group.

◆ ZSOCK_IPV6_LEAVE_GROUP

#define ZSOCK_IPV6_LEAVE_GROUP ZSOCK_IPV6_DROP_MEMBERSHIP

#include <zephyr/net/socket.h>

Leave IPv6 multicast group.

◆ ZSOCK_IPV6_MTU

#define ZSOCK_IPV6_MTU 24

#include <zephyr/net/socket.h>

For getsockopt(), retrieve the current known IPv6 path MTU of the given socket.

Valid only when the socket has been connected. For setsockopt(), set the MTU to be used for the socket. The MTU is limited by the device MTU or the path MTU when path MTU discovery is enabled.
