[upnp-sdk-dev] building a combo of control point and device

[gokeigen <go...@so...>]

I have a problem when i build control point and device into one process.
source code is listed down.If the function of "UpnpSendAdvertisement"is 
called,the control point can not download description document from mini
http server.But,if "UpnpSendAdvertisement"is not called,everything is
ok.what is wrong with my program?

/* routine */
int upnpDeviceStart()
{
	int ret = UPNP_E_SUCCESS;
	char* web_dir_path = "./web";
	
	ret = UpnpSetWebServerRootDir(web_dir_path);
	if(ret != UPNP_E_SUCCESS)
	{
		ERROR_PRINTF("Specifying webserver root directory --> %s  failure!\n
\
						Error Code : %d\n",web_dir_path,ret);
		upnpFinish();
		return ret;		
	}
	
	char* ip = NULL;
	unsigned short port;
	char desc_File_url[256];
	char* pDesc_File_Name = "tvdevicedesc.xml";
	
	ip = UpnpGetServerIpAddress();
	port = UpnpGetServerPort();
	
	sprintf(desc_File_url,"http://%s:%d/%s",ip,port,pDesc_File_Name);
	DBG_PRINTF("descfileurl --> %s\n",desc_File_url);
	
	ret = UpnpRegisterRootDevice(desc_File_url,
								 upnpDeviceCallbackEventHandler,
								 &deviceHandle,
								 &deviceHandle);
	if(ret != UPNP_E_SUCCESS)
	{
		ERROR_PRINTF("Registering the rootdevice --> %s failure!\n 	\
						Error Code : %d\n",&desc_File_url[0],ret);		
		upnpFinish();
		return ret;									
	}			
#if 1
	ret = UpnpSendAdvertisement(deviceHandle,Device_Advr_Expire);
	if(ret != UPNP_E_SUCCESS)
	{
		ERROR_PRINTF("Sending advertisements --> %d\n \
					 Error Code : %d\n",ret);
		upnpFinish();
		return ret;					 
	}
#endif						 
	return ret;
}
