status.i4.v = dio_cancel_set_array_c(device_index.i4.v, property.i2.v,

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

	device_index	device index
	property	property index (constants are in 'dbprops')
	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

	Related functions:

	dio_set_array_device_c, dio_set_dev(_c), dio_set_raw(_c),
	dio_can_set(_c), dio_delete_requests_c, dio_flush

	C/C++ usage:

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

	status = dio_cancel_set_array_c(device_index,property,
