Function Documentation

pj_status_t pjsip_endpt_respond	(	pjsip_endpoint *	endpt,
		pjsip_module *	tsx_user,
		pjsip_rx_data *	rdata,
		int	st_code,
		const pj_str_t *	st_text,
		const pjsip_hdr *	hdr_list,
		const pjsip_msg_body *	body,
		pjsip_transaction **	p_tsx
	)

This composite function creates and sends response statefully for the incoming request.

Parameters:

	endpt	The endpoint instance.
	tsx_user	The module to be registered as transaction user.
	rdata	The incoming request message.
	st_code	Status code of the response.
	st_text	Optional status text of the response.
	hdr_list	Optional header list to be added to the response.
	body	Optional message body to be added to the response.
	p_tsx	Optional pointer to receive the transaction which was created to send the response.

Returns:

PJ_SUCCESS if response message has successfully been created.

pj_status_t pjsip_endpt_send_request	(	pjsip_endpoint *	endpt,
		pjsip_tx_data *	tdata,
		pj_int32_t	timeout,
		void *	token,
		pjsip_endpt_send_callback	cb
	)

Send outgoing request and initiate UAC transaction for the request. This is an auxiliary function to be used by application to send arbitrary requests outside a dialog. To send a request within a dialog, application should use pjsip_dlg_send_request instead.

Parameters:

	endpt	The endpoint instance.
	tdata	The transmit data to be sent.
	timeout	Optional timeout for final response to be received, or -1 if the transaction should not have a timeout restriction. The value is in miliseconds.
	token	Optional token to be associated with the transaction, and to be passed to the callback.
	cb	Optional callback to be called when the transaction has received a final response. The callback will be called with the previously registered token and the event that triggers the completion of the transaction.

Returns:

PJ_SUCCESS, or the appropriate error code.
