Example #1

File: NetNodeServer.cpp Project: AnimationInVR/avango

void
av::NetNodeServer::cast(av::Msg& av_msg)
{
  zmq::message_t zmq_message(av_msg.getSize());
  memcpy(zmq_message.data(), av_msg.getBuffer(), av_msg.getSize());
  mSocket.send(zmq_message);
}

Example #2

void osg::av_popMsg(av::Msg& netMsg, ::osg::Vec2f& buf)
{
    ::osg::Vec2f b;
    XDR xdr;

    xdrmem_create(&xdr, (caddr_t)&b, sizeof(b), XDR_DECODE);

    xdr_vector(&xdr, (char*)&buf, 2, sizeof(float), (xdrproc_t)xdr_float);
    xdr_destroy(&xdr);
}

Example #3

void osg::av_popMsg(av::Msg& netMsg, ::osg::Matrixd& buf)
