C++ (Cpp) CloseStreamImpl Examples

Example #1

File: XnServerSession.cpp Project: roxlu/SensorKinect

XnStatus XnServerSession::HandleCloseStream()
{
	XnStatus nRetVal = XN_STATUS_OK;

	// read it
	XnChar strStreamName[XN_DEVICE_MAX_STRING_LENGTH];
	XnUInt32 nDataSize = XN_DEVICE_MAX_STRING_LENGTH;
	XnUInt32 nType = XN_SENSOR_SERVER_MESSAGE_CLOSE_STREAM;
	nRetVal = m_privateIncomingPacker.ReadCustomData(nType, strStreamName, &nDataSize);
	XN_IS_STATUS_OK(nRetVal);

	XnStatus nActionResult = CloseStreamImpl(strStreamName);

	nRetVal = SendReply(XN_SENSOR_SERVER_MESSAGE_GENERAL_OP_RESPOND, nActionResult);
	XN_IS_STATUS_OK(nRetVal);

	return (XN_STATUS_OK);
}

Example #2

File: XnServerSession.cpp Project: RikeshThapa/VirtueX

XnStatus XnServerSession::RemoveStreamImpl(const XnChar* strName)
{
	XnStatus nRetVal = XN_STATUS_OK;

	SessionStream* pStream = NULL;
	nRetVal = m_streamsHash.Get(strName, pStream);

	if (pStream->bIsOpen)
	{

		XN_IS_STATUS_OK(nRetVal);
		pStream->bIsOpen = FALSE;
	}

	// release that stream
	nRetVal = m_pSensor->ReleaseStream(pStream->strStreamName);
	XN_IS_STATUS_OK(nRetVal);

	// if client had a buffer of this stream, release it
	XnStreamData* pStreamData = NULL;
	nRetVal = XnStreamDataSetGet(m_pStreamDataSet, pStream->strStreamName, &pStreamData);

	// now remove it from client
