I have a Raspberry Pi that reads sensor data and I would like to send it to a xively feed.
I figured out that I have to use either the API or the C library. I failed trying to use the library.
I would like to have something like this in my C++ program:
xively.update("sensor1",sensorvalue);
What is the easiest way to do that?
Xively C library currently doesn't implement a high-level C++ wrapper.
You need to statically link with libxively.a.
I have just answered on the original question.

I made a simple C++ game server library(network session) and I wanted to use it for Unity client to make a simple MMORPG.
I found that my library needs to be changed to DLL.
So, I made a dll of my C++ game server library and found that my class cannot be used for Unity Client directly.
Is there an easy way to use my c++ library class for Unity Client?
I hope your wise answers.
Thank you for reading.
You are trying to create a Unity native plugin. You have to make sure that you export your methods in the proper way and then you can "link" them to a C# method that will have the same signature. Tip: make sure to keep with the native/primitive types. Since it is a long topic to be explained here I am sharing a link that will help you:

I'm trying to make a c++ snake game in linux using ansi escape codes but i can't figure out a way to get async keyboard input. Im a beginner and i'm currently reading a c++ book, so i didn't cover multithreading yet.
Is there any chance to achieve this result in a "simple" way.(and standard if it's possible, i saw the kbhit solution)
How to use kbhit and getch (C programming)
. Can i solve the problem reading from the /dev/input event files?
Thank you guys.
C++ does not offer a standard way to asynchronously read the keyboard status.
boost asio, as in read from keyboard using boost async_read and posix::stream_descriptor is one way. Some people consider boost like a "standard" or "normal" C++ extension.
Another way is to use a game library like SDL or SFML. You include their headers and you link with their libs.
I want to pass kinect data from one computer to another computer.I got the sample source from codeplex. It is a C# application.So C# applications can directly use this library as it is.But i am coding in C++,how can i use the above code in c++ windows application.

I want to write a program to create VOIP application for my final year project. For this time being, I spend my time to understand how SIP works and later I need to implement it into my project. As far as i know, the protocol requirement to build this project are:
UDP
RTP
As for my project, it doesn't requires me to write a complex coding. I just need to provide a server that can be used as a bridge for clients to communicate. So, is there any resources that I can used for my reference to start programming my project?
Maybe these will be helpful to look at:
Open source RTP library:
jrtplib:
Open source RTSP, RTP with a SIP client AFAIR:
liveMedia
Open source SIP library: reSIProcate
Your best bet is pjsip.
http://www.pjsip.org/
It runs on all kinds of OSes
OpenSipStack is quite nice, it's 100% C++.
The project also contains a library for creating clients using ATL.
Take a look at OPAL. It allows you to write applications that will support SIP, H.323 and IAX2.
Specifically I am talking about using AIM and sending instant messages to an existing AIM screename. How would I accomplish this? I am trying to do it the simplest way possible -efficiency is not that important.
I thought maybe all I would have to do is open a socket connections some how but I am probably wrong.
I would use libpurple. It's a multi-platform C library that supports many IM services, including AIM.
Check out the source for GAIM/Pidgin, which runs on a variety of platforms including windows. It uses a modified version of libfaim.
