status.i4.v = dio_cancel_get_array_c(device_index.i4.v, property.i2.v,
					     ftd.i2.v, num_entries.i4.v,

	This routine cancels a read request for a single array device.

	device_index	device index
	property	property index (constants are in 'dbprops')
	ftd		Frequency Time Descriptor
			(FTD_ONESHOT -> one shot,
			 FTD_DEFAULT -> use database default FTD,
			 FTD_1HZ -> 1 Hz request (Note: This value can be
				    multiplied by an integer constant to
				    retrieve data every "constant" seconds.),
			 FTD_EVENT_MASK OR'ed with TCLK event value -> read
			 on TCLK event (event constants are in 'tclk_events')
			 (can use the macro BUILD_EVENT_FTD(event) or
			  BUILD_EVENT_PLUS_DELAY_FTD(event,delay) in 'macro'))
	num_elements	number of array elements
	start_element	first array element

	This function returns ACNET status values as follows:

	OK			success
	DIO_CANFAIL		entry not found
	DIO_UNAVAIL		not valid in this context (MIO in use)
	DIO_INVDEV		not an array device
	DIO_BADARG		invalid array element specified

	This function requires the following include files:

	dbprops_h, diolib_h, acnet_errors_h, tclk_events_h, macro_h

	C/C++ usage:

	short	property = PRSET;
	short	ftd = FTD_1HZ;
	int	status;
	int	device_index = 14430;
	int	num_elements = 64;
	int	start_element = 0;
