PCDROM_ERROR_HANDLER()
Routine Description:
This routine is a callback into the driver to handle errors. The queue shall not be unfrozen when this error handler is called, even though the SRB flags may mark the queue as having been frozen due to this SRB.
Irql:
This routine will be called at KIRQL <= DISPATCH_LEVEL
Arguments:
DeviceObject is the device object the error occurred on.
Srb is the Srb that was being processed when the error occurred.
Status may be overwritten by the routine if it decides that the error was benign, or otherwise wishes to change the returned status code for this command
Retry may be overwritten to specify that this command should or should not be retried (if the callee supports retrying commands)
Return Value:
