Message handler.
This function is called once for each message in the incoming queue. Reimplement it to provide message handling. Return 0 if you handled the message and -1 otherwise
- Parameters:
-
resp_queue The queue to which any response should go. hdr The message header data The message body

Main method for driver thread.
drivers have their own thread of execution, created using StartThread(); this is the entry point for the driver thread, and must be overloaded by all threaded drivers.
