dio_has_property_c

	status.i4.v = dio_has_property_c(device_index.i4.v, property.i2.v)

	This routine determines whether or not a given device has the
	requested property.

	device_index	device index
	property	property to check for
			(PRREAD -> reading property,
			 PRSET -> setting property,
			 PRBSTS -> basic status property,
			 PRBCTL -> basic control property,
			 PRANAB -> analog alarm property,
			 PRDABL -> digital alarm property,
			 PRNAME -> device name property,
			 PRNODE -> device node property,
			 PRTEXT -> device description property,
			 PRSIBL -> sibling(s) property,
			 PRSAVE -> save/restore information property,
			 PRAATX -> analog alarm text property,
			 PRDATX -> digital alarm text property,
			 PRETXT -> extended (bit) text property,
			 PRFMLY -> family or SSDR (SubSystem Device Record) property,
			 PREMC -> EMC (Event Message Code) property)
			(property constants are in 'dbprops')

	This function returns status values as follows:

	TRUE			device has this property
	FALSE			device does not have this property
	negative value		ACNET format error code

	This function requires the following include files:

	cnsparam_h, dbprops_h, diolib_h, acnet_errors_h
