status.i4.v = dio_is_controlled_set_c(device_index.i4.v,

	This routine checks to see if the present device has a controlled
	setting.  Devices having a controlled setting cannot be set from
	the parameter page and some other generic programs.
	device_index	device index
	is_controlled	returned controlled setting status
			(TRUE -> device's setting is controlled,
			 FALSE -> device's setting is not controlled,
			 DIO_INVALID_DATA -> error occurred in reading data)
	[property]	property to check
			(PRSET -> setting property (default),
			 PRBCTL -> basic control property,
			 PRANAB -> analog alarm property,
			 PRDABL -> digital alarm property)

	This function returns ACNET status values as follows:

	OK			success
	DIO_BADARG		invalid property
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error

	This function requires the following include files:

	cnsparam_h, diolib_h, dbprops_h, acnet_errors_h
