protectedvirtual |
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.
Implements ThreadedDriver.
|
protectedvirtual |
Cleanup method for driver thread (called when main exits)
Overload this method and to do additional cleanup when the driver thread exits.
Reimplemented from ThreadedDriver.
|
virtual |
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
| resp_queue | The queue to which any response should go. |
| hdr | The message header |
| data | The message body |
Reimplemented from Driver.
