dio_is_enum_value_info_shared_c

	status.i4.v = dio_is_enum_value_info_shared_c(device_indices.i4a.r,
						      properties.i2a.r,
						      shared_count.u4a.r,
						      errors.i2a.r
						      [,num_devices.i4.v])

	This routine determines if reading/setting enumerated value
	information for a device is shared with other devices.

	device_indices	device index or array of device indices
	properties	property index or array of property indices
			(PRREAD -> reading property,
			 PRSET -> setting property)
			(If the first value is less than zero, all devices
			 will be requested with a property index which is
			 equal to the absolute value of this argument.)
	shared_count	returned number of devices/properties sharing
			this enumerated value set with the requested device
	errors		returned ACNET status value or array of 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 passed
	DIO_MEMFAIL		memory allocation failure
	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, cns_data_structs_h, acnet_errors_h

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

	status = dio_is_enum_value_info_shared_c(device_indices,properties,
						 shared_count,errors,
						 num_devices);
