The GetPnPServiceID method retrieves a Plug and Play (PnP) identifier for the service.

Syntax


HRESULT STDMETHODCALLTYPE GetPnPServiceID(
  [out] LPWSTR *ppszPnPServiceID
);

ppszPnPServiceID [out]: The retrieved PnP identifier, which is the same identifier that was passed to the Open method.

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_POINTER	A NULL parameter was specified.
E_WPD_SERVICE_NOT_OPEN	The Open method has not yet been called for the service.

The Open method must be called on the service before a PnP identifier can be retrieved.

When an application no longer needs the PnP identifier, it should call the CoTaskMemFree function to free the identifier memory.
