Could you any one help me to use the "UpnpNotifyExt()" API. I am very clear from the document, what the API will do, but I need some help to understand the second and third argument ( DevID, ServID).
In the Overall UPnP API the DevID and ServID not available to Application directly, So could any how tell me how to use these argument.
Example : I want to notify the TransportState through LastChange variable in AVT Service.
Thanks in Advance
