dio_duplicate_ssdn_properties_c

	status.i4.v = dio_duplicate_ssdn_properties_c(device_index.i4.v,
						      property.i2.v,
						      options.u4.v,
						      num_duplicates.i4.r,

	This routine returns device properties whose SSDNs are
	the same as the requested device and originate from the
	same front end.

	device_index	device index
	property	property index (Passing a value of PRNULL for this
			argument will result in all of the device's properties
			being checked.)
			(constants are in 'dbprops')
	options		search options
			(DIO_OPT_NONE -> no options selected)
	num_duplicates	returned number of duplicate properties found
	device_indices	returned matching device indices
			(The memory for these values is allocated by this
			 routine and should be freed by the caller.)
			(A value of NULL can be passed for this argument
			 if the device indices are not needed.)
	properties	returned matching properties
			(The memory for these values is allocated by this
			 routine and should be freed by the caller.)
			(A value of NULL can be passed for this argument
			 if the properties are not needed.)

	This function returns ACNET status values as follows:

	OK			success
	SQL_xxx			error retrieving duplicate SSDN properties

	This function requires the following include files:

	diolib_h, acnet_errors_h

	C/C++ usage:

	short	property = PRSET;
	short	*properties;
	int	status;
	int	device_index = 4976;
	int	num_duplicates;
	int	*device_indices;
	unsigned int	options = DIO_OPT_NONE;

	status = dio_duplicate_ssdn_properties_c(device_index,property,options,
						 &num_duplicates,
						 &device_indices,&properties);
