What's New in the UPnP APIs
The UPnP™ APIs have new features and updated documentation for Windows XP SP2. The following table identifies the new documentation.
| Feature | Description |
|---|---|
| IUPnPRemoteEndpointInfo | This new interface allows a hosted device to obtain information about a requester (that is, a control point) and the request. It includes three methods, each of which provides a different type of information. |
| Implementing Device Behavior | This topic includes a new section that explains how to obtain endpoint information by using the new IUPnPRemoteEndpointInfo interface. |
| Configuration Settings | This new topic provides information about the registry settings that affect the behavior of the UPnP APIs. |
| Device Error Codes | This new topic explains how an error code from a device is converted to an HRESULT value and vice versa. An understanding of this process is necessary in order to evaluate an HRESULT value that is returned by the IUPnPService::InvokeAction and IUPnPService::QueryStateVariable methods. |
