[Applies to KMDF and UMDF]
The WdfObjectReference macro increments the reference count for a specified framework object.
Syntax
VOID WdfObjectReference(
[in] WDFOBJECT Handle
);
Parameters
Handle [in]
A handle to a framework object.
Return value
None.
A bug check occurs if the driver supplies an invalid object handle.
Remarks
If your driver calls WdfObjectReference to increment a reference count, the driver must call WdfObjectDereference to decrement the count.
Instead of calling WdfObjectReference, a driver can call WdfObjectReferenceWithTag or WdfObjectReferenceActual.
For more information about object reference counts, see Framework Object Life Cycle.
Examples
The following code example increments an object's reference count.
WdfObjectReference(Object);
