WSD 挑战者功能已弃用，所有与 WSD 挑战者相关的文档将在 2018 年删除。

以下代码显示了本部分代码示例中使用的常量定义和常见变量。

//
// WSD Challenge DLL name (including a forward path separator) and public API names

#define WSDCHNR_REGISTER_DEVICE_TO_CHALLENGE "WSDCHNGRRegisterDeviceToChallenge"

typedef HRESULT (*PFN_WSDCHNR_REGISTER_DEVICE_TO_CHALLENGE)(__in IFunctionInstance *pFunctionInstance);

//
// The instance module of the WSD Challenge DLL (WSDCHNGR.DLL)
