The README.developer sample code shows the dissector callback function
as shown:

/* Code to actually dissect the packets */
static int
dissect_PROTOABBREV(tvbuff_t *tvb, packet_info *pinfo, proto_tree *tree)
{

/* ... */

/* Return the amount of data this dissector was able to dissect */
	return tvb_length(tvb);
}

However, other source shows this function as having return type static
void.  Is it not necessary to return the number of bytes the dissector
processed any longer?

Thanks,

- -Josh
