Function Documentation

void liveViz0Get	(	const liveVizRequest &	req,
		void *	data,
		int	dataLen
	)

Called when the client requests an image as described above.

You must implement this routine, which will be called from a single processor. data and dataLen are additional data supplied with the CCS request. This routine is called on the processor where the request arrives; this is normally processor 0.

void liveViz0Deposit	(	const liveVizRequest &	req,
		byte *	imageData
	)

Each call to liveViz, above, must eventually result in a call to this routine, which delivers an entire, finished image to the client.

Begin responding to image requests under the given configuration.

liveViz0Init should be called exactly once on processor 0 when your program is ready to begin processing image requests.
