            task_out_stream: Specifies the output stream associated with
                an NI-DAQmx task which to write samples.
            auto_start (Optional[bool]): Specifies if the write method
                automatically starts the task if you did not explicitly
                start it with the DAQmx Start Task method.

                If you do not specify a value for this parameter, 
                NI-DAQmx determines its value based on the type of write
                method used. If you use a one sample write method, the
                value is True; conversely, if you use a many sample 
                write method, the value is False.
