To control whether exceeding this threshold should cause a debug break or a bugcheck, set the DbgBreakOnError key.īy default, if the ObjectsForLeakDetection key is not specified, the framework monitors WDFREQUEST, WDFWORKITEM, WDFKEY, WDFSTRING, WDFOBJECT, and WDFDEVICE. To specify all handle types, use * as the string. For example, you could specify WDFDMATRANSACTION WDFDEVICE. This is the maximum number of objects of the types described in the ObjectsForLeakDetection key.Īdd a new REG_MULTI_SZ value named ObjectsForLeakDetection that lists each type name to verify.
