WdfRegistryClose function (wdfregistry.h)
[Applies to KMDF and UMDF]
The WdfRegistryClose method closes the registry key that is associated with a specified framework registry-key object and then deletes the registry-key object.
Syntax
void WdfRegistryClose(
[in] WDFKEY Key
);
Parameters
[in] Key
A handle to a registry-key object that represents an opened registry key.
Return value
None
Remarks
A bug check occurs if the driver supplies an invalid object handle.
After your driver has finished accessing a registry key, it must call WdfRegistryClose or WdfObjectDelete. Both of these methods close the registry key and delete the registry-key object.
For more information about registry-key objects, see Using the Registry in Framework-Based Drivers.
Examples
The following code example closes a registry key and deletes the registry-key object.
WdfRegistryClose(Key);
