dio_status_scaling_length_c

	status.i4.v = dio_status_scaling_length_c(device_indices.i4a.r,
						  scaling_length.i4a.r,
						  errors.i2a.r
						  [,num_devices.i4.v])

	This routine returns the status scaling length for a device or
	a list of devices.
	
	device_indices	device index or array of device indices
	scaling_length	returned status scaling length(s) in bytes
	errors		returned ACNET status value or array of returned
			status values
	[num_devices]	number of devices (default is 1)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid number of devices
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error
	positive value		number of devices in error

	This function requires the following include files:

	diolib_h, acnet_errors_h

	Related functions:

	dio_control_scaling_length_c, dio_scaling_len(_c),
	dio_scaling_length_list_c, dio_manage_pdbs_c,
	dio_scaling, error_in_list(_c)

	C/C++ usage:

	short	errors[NUM_DEVICES];
	int	status;
	static const int	device_indices[NUM_DEVICES] = {14430, 14431};
	int	scaling_length[NUM_DEVICES];
	int	num_devices = NUM_DEVICES;

	status = dio_status_scaling_length_c(device_indices,scaling_length,
					     errors,num_devices);
