status.i4.v = c475_device_type_c(device_names.i1a.r, device_types.i4a.r,
					 errors.i2a.r [,num_devices.i4.v])

	This routine returns device types for requested C475 devices.

	names		device names
			(dio_get_terse_name_length characters per device)
	device_types	returned device type or array of device types
			(WG_FAMILY_DEVICE -> family of waveform devices,
			 WG_MAIN_DEVICE -> main parameter page device,
			 WG_TIME_DEVICE -> time table device,
			 WG_MAP_DEVICE -> map device,
			 WG_SF_DEVICE -> scale factor device,
			 WG_VERSION_DEVICE -> version device,
			 WG_MUX_DEVICE -> mux device,
			 WG_GI_DEVICE -> G(I) table device,
			 WG_HI_DEVICE -> H(I) table device,
			 WG_GI_ABSC_DEVICE -> G(I) current table device,
			 WG_HI_ABSC_DEVICE -> H(I) current table device,
			 WG_CLOCK_DEVICE -> clock event table device,
			 WG_MDAT_DEVICE -> MDAT selection device,
			 WG_OFFSET_DEVICE -> offset table device,
			 WG_DELAY_DEVICE -> delay table device,
			 WG_FREQUENCY_DEVICE -> frequency table device,
			 WG_PHASE_DEVICE -> phase table device)
	errors		returned device error or array of errors
			(OK -> success,
			 DIO_INVDEV -> not a supported C475 device) 
	[num_devices]	number of devices (default is 1)

	This function returns ACNET status values as follows:

	OK			success
	DIO_xxx			error retrieving database info
	positive value		number of devices in error

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, acnet_errors_h

	C/C++ usage:

	static const char	device_names[NUM_DEVICES*DEVICE_TERSE_NAME_LEN+1] =
	"B:XQ1   B:XQ2   ";
	short	errors[NUM_DEVICES];
	int	status;
	int	device_types[NUM_DEVICES];
	int	num_devices = NUM_DEVICES;
