Detailed Description

This module includes functions for UDP forward feature.

The functions in this module are available when udp-forward feature (OPENTHREAD_CONFIG_UDP_FORWARD_ENABLE) is enabled.

Typedef Documentation

typedef void(* otUdpForwarder)(otMessage *aMessage, uint16_t aPeerPort, otIp6Address *aPeerAddr, uint16_t aSockPort, void *aContext)

This function pointer delivers the UDP packet to host and host should send the packet through its own network stack.

Parameters
[in]aMessageA pointer to the UDP Message.
[in]aPeerPortThe destination UDP port.
[in]aPeerAddrA pointer to the destination IPv6 address.
[in]aSockPortThe source UDP port.
[in]aContextA pointer to application-specific context.

Function Documentation

void otUdpForwardReceive ( otInstance aInstance,
otMessage aMessage,
uint16_t  aPeerPort,
const otIp6Address aPeerAddr,
uint16_t  aSockPort 
)

Handle a UDP packet received from host.

Parameters
[in]aInstanceA pointer to an OpenThread instance.
[in]aMessageA pointer to the UDP Message.
[in]aPeerPortThe source UDP port.
[in]aPeerAddrA pointer to the source address.
[in]aSockPortThe destination UDP port.
Warning
No matter the call success or fail, the message is freed.
void otUdpForwardSetForwarder ( otInstance aInstance,
otUdpForwarder  aForwarder,
void *  aContext 
)

Set UDP forward callback to deliver UDP packets to host.

Parameters
[in]aInstanceA pointer to an OpenThread instance.
[in]aForwarderA pointer to a function called to forward UDP packet to host.
[in]aContextA pointer to application-specific context.
otUdpSocket* otUdpGetSockets ( otInstance aInstance)

This function gets the existing UDP Sockets.

Parameters
[in]aInstanceA pointer to an OpenThread instance.
Returns
A pointer to the first UDP Socket.
