status.i4.v = dio_is_family_list_c(device_indices.i4a.r,
					   is_family.i4a.r, errors.i2a.r,

	This routine determines whether or not a list of devices are
	family devices.

	device_indices	array of device indices to check
	is_family	returned array of family device status values
			(TRUE -> device is a family device,
			 FALSE -> device is not a family device)
	errors		returned array of ACNET status values
	num_devices	number of devices

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid number of devices passed
	negative value		ACNET format error indicating overall failure
	positive value		number of devices in error indicating partial

	This function requires the following include files:

	cnsparam_h, diolib_h

	Related functions:

	dio_is_family, dio_family, dio_expand_family_c, dio_family_info(_c),

	C/C++ usage:

	short	errors[NUM_DEVICES];
	int	status;
	static const int	device_indices[NUM_DEVICES] = {48443, 48444};
	int	is_family[NUM_DEVICES];
	int	num_devices = NUM_DEVICES;

	status = dio_is_family_list_c(device_indices,is_family,errors,
