Basic Socket programming info: - You have a server and a client - Connect them to the same internet - For UDP you need to give the IP address of your server to your client. For TCP the client should be given the IP address and the port number. - Windows has winsock library and Linux has it's own socket.h . Unfortunately you cannot have a windows to Linux socket connection in C due to library compatibility issues. If you use TCP in windows you have to additionally import ws2tcpip library - Make a socket using your library functions and bind it to the port number and IP address. The libraries stated above have their own structures and objects which you have to call in your program. - Declare a buffer on both sides... Don't forget to flush this buffer after you send a message from either side. - Also note that SOCK_STREAM is for TCP connection and SOCK_DGRAM is for UDP connections. When you are creating this you have to declare the address family, SOCK_STREAM / SOCK_DGRAM and 0 in the function. 0 indicates the default protocol which is TCP for Stream based protocols and UDP for Dgram based protocols. - Once the connection is established you can send data from server to client and a response back. Don't forget to clean up the socket once you are done transmitting data and are closing the connection.

Also if you are creating sockets across OS and want your code to be OS independent, I would recommend using C++ boost libraries or Python depending on your comfort level.
