dio_is_old_name(_c)

	status.i4.v = dio_is_old_name_c(old_device_name.i1a.r,
					device_name.i1a.r,
					device_index.i4.r [,options.i4.v])

	This routine determines if a string is a former name of a current
	device.  A value of NULL can be passed for any returned parameters
	which are not needed.

	old_device_name	possible old device name
			(dio_get_terse_name_length or DEVICE_FULL_NAME_LEN
			 characters)
	device_name	returned current device name
			(dio_get_terse_name_length or DEVICE_FULL_NAME_LEN
			 characters)
	device_index	returned device index
	[options]	device name retrieval options
			(DIO_NAME_OPT_NONE -> no options selected (default),
			 DIO_NAME_OPT_FULL_NAME -> retrieve the full name,
			 DIO_NAME_OPT_ALLOW_OBSOLETE -> want device indices of
							obsoleted and deleted
							devices)

	This function returns status values as follows:

	TRUE			passed name was a former device name
	FALSE			passed name was not a former device name
	otherwise		database access error

	This function requires the following include files:

	cnsparam_h, diolib_h, acnet_errors_h

	char		device_name[DEVICE_TERSE_NAME_LEN];
	int		status;
	int		device_index;
	int		options = DIO_NAME_OPT_ALLOW_OBSOLETE;

	status = dio_is_old_name_c(old_device_name,device_name,&device_index,
				   options);
