status.i4.v = dio_enum_value_shared_devices_c(device_indices.i4a.r,

	This routine returns devices which share reading/setting enumerated
	value information with a device.  The number of shared devices is
	returned in "num_entries".  If "num_devices" is specified, enumerated
	value information for a list of devices can be retrieved.

	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.)
	num_entries	returned number of shared device entries or
			array of number of shared device entries (A value of
			NULL may be passed if no entry counts are needed.)
	shared_devices	returned array of corresponding shared device
			entries (array of structures of type
			DIO_DEVICE_PROPERTY_DATA) (The memory for this argument
			is allocated by this routine and should be freed by
			the caller.) (A value of NULL may be
			passed if no actual shared device entries are
	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

	This function requires the following include files:

	cnsparam_h, diolib_h, cns_data_structs_h, acnet_errors_h
