** I'm mostly looking for examples of what exactly are passed into the dissect_protocol() functions.
What's passed to them are the arguments they expect - a pointer to a tvbuff with the part of the packet data that it should dissect, a pointer to a packet_info structure with various information to be used by or filled in by dissecting, and a possibly-null pointer to a portion of the protocol tree to be filled in. 

See README.developer, as suggested by others.
