成功完成后返回ERROR_SUCCESS。下表列出了常见的错误。

Return code	Description
ERROR_INVALID_PARAMETER	The dwServiceFlags are not valid.      dwServiceFlags无效。
ERROR_SERVICE_DOES_NOT_EXIST	The GUID specified in pGuidService is not supported.   不支持pGuidService中指定的GUID
E_INVALIDARG	dwServiceFlags is set to BLUETOOTH_SERVICE_DISABLE and the service is already disabled, or dwServiceFlags is set to BLUETOOTH_SERVICE_ENABLE and the service is already enabled. dwServiceFlags设置为BLUETOOTH_SERVICE_DISABLE，服务已经禁用，或者dwServiceFlags设置为BLUETOOTH_SERVICE_ENABLE，服务已经启用

 

Windows维护了服务全局惟一标识符(GUIDs)到支持蓝牙设备的驱动程序的映射。启用服务将安装相应的设备驱动程序，禁用服务将删除相应的设备驱动程序。如果启用了不支持的服务，则不会安装驱动程序。
