This module includes functions for UDP forward feature.

Typedefs
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.

Functions
void	otUdpForwardSetForwarder ( otInstance aInstance, otUdpForwarder aForwarder, void aContext)
	Set UDP forward callback to deliver UDP packets to host.

void	otUdpForwardReceive ( otInstance aInstance, otMessage aMessage, uint16_t aPeerPort, const otIp6Address *aPeerAddr, uint16_t aSockPort)
	Handle a UDP packet received from host.

bool	otUdpIsPortInUse ( otInstance *aInstance, uint16_t port)
	Determines if the given UDP port is exclusively opened by OpenThread API.

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]	`aMessage`	A pointer to the UDP Message.
[in]	`aPeerPort`	The destination UDP port.
[in]	`aPeerAddr`	A pointer to the destination IPv6 address.
[in]	`aSockPort`	The source UDP port.
[in]	`aContext`	A pointer to application-specific context.

Handle a UDP packet received from host.

Parameters

[in]	`aInstance`	A pointer to an OpenThread instance.
[in]	`aMessage`	A pointer to the UDP Message.
[in]	`aPeerPort`	The source UDP port.
[in]	`aPeerAddr`	A pointer to the source address.
[in]	`aSockPort`	The destination UDP port.

void otUdpForwardSetForwarder	(	otInstance *	`aInstance,`
		otUdpForwarder	`aForwarder,`
		void *	`aContext`
	)

Set UDP forward callback to deliver UDP packets to host.

Parameters

[in]	`aInstance`	A pointer to an OpenThread instance.
[in]	`aForwarder`	A pointer to a function called to forward UDP packet to host.
[in]	`aContext`	A pointer to application-specific context.

Determines if the given UDP port is exclusively opened by OpenThread API.

Parameters

[in]	`aInstance`	A pointer to an OpenThread instance.
[in]	`port`	UDP port number to verify.

Return values

`true`	The port is being used exclusively by OpenThread.
`false`	The port is not used by any of the OpenThread API or is shared (e.g. is Backbone socket).
