dio_is_family_list_c

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

	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
				success

	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),
	error_in_list(_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,
				      num_devices);
