dio_step_motor_is_moving_c

	status.i4.v = dio_step_motor_is_moving_c(device_index.i4.v)

	This routine determines if a stepping motor device is presently moving.
	
	device_index	device index

	This function returns status as follows:

	TRUE			stepping motor is moving
	FALSE			stepping motor is not moving
	DIO_INVALID_DEVICE_TYPE	device is not a stepping motor
	otherwise		ACNET error code

	This function requires the following include files:

	cnsparam_h, diolib_h, acnet_errors_h

	Related functions:

	dio_is_step_motor, dio_set_step_motor(_c), dio_set_step_motor_steps_c,
	dio_move_step_motor

	C/C++ usage:

	int	status;
	int	device_index = 5122;

	status = dio_step_motor_is_moving_c(device_index);
