You can use the GetEvent function to query the driver for run-time statistics. The GetEvent function takes four arguments:
- Type of event
- A pointer for the output data buffer
- A pointer for the output data buffer length
- A target table index. The target table index argument is only used by the Update and Stream drivers.
conn->GetEvent(eventType,eventData,&eventDataLen,tableIndex);
Call the GetEvent method after the driver initiates and before it terminates. Some events require the job to reach a certain point before their data becomes available. If the job has not yet reached this point, the GetEvent method returns TD_Unavailable.
