Field Documentation

void(* pj_stun_tsx_cb::on_complete)(pj_stun_client_tsx *tsx, pj_status_t status, const pj_stun_msg *response, const pj_sockaddr_t *src_addr, unsigned src_addr_len)

This callback is called when the STUN transaction completed.

Parameters:

	tsx	The STUN transaction.
	status	Status of the transaction. Status PJ_SUCCESS means that the request has received a successful response.
	response	The STUN response, which value may be NULL if status is not PJ_SUCCESS.
	src_addr	The source address of the response, if response is not NULL.
	src_addr_len	The length of the source address.

void(* pj_stun_tsx_cb::on_destroy)(pj_stun_client_tsx *tsx)

This callback is called after the timer that was scheduled by pj_stun_client_tsx_schedule_destroy() has elapsed. Application should call pj_stun_client_tsx_destroy() upon receiving this callback.

This callback is optional if application will not call pj_stun_client_tsx_schedule_destroy().

Parameters:

tsx

The STUN transaction instance.

pj_status_t(* pj_stun_tsx_cb::on_send_msg)(pj_stun_client_tsx *tsx, const void *stun_pkt, pj_size_t pkt_size)

This callback is called by the STUN transaction when it wants to send outgoing message.

Parameters:

	tsx	The STUN transaction instance.
	stun_pkt	The STUN packet to be sent.
	pkt_size	Size of the STUN packet.

Returns:

If return value of the callback is not PJ_SUCCESS, the transaction will fail. Application MUST return PJNATH_ESTUNDESTROYED if it has destroyed the transaction in this callback.
