void ImageBase::Main ( ) [protected, virtual]

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.

void ImageBase::MainQuit ( void  ) [protected, virtual]

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.

int ImageBase::ProcessMessage ( QueuePointer resp_queue,
player_msghdr hdr,
void *  data 
) [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_queueThe queue to which any response should go.
hdrThe message header
dataThe message body

Reimplemented from Driver.
