Does any one know how to make a program with lan connections???

Check network programming in general; most LAN networks use TCP/IP, i.e. the same protocol as with WAN (internet and stuff).

If you're working with windows, check the winsock documentation.

Maybe Socket Programming??

You would have to do some socket programming. In Windowz (wich I loath) you can use Winsock. If you are using a Unix I recommend reading Beej's guide. Just google "Beej's"

Beej guide also apply to Winsock if you can do without async sockets. Most people learning sockets can.

If you're using Cygwin under Windows then you can use Unix sockets due to the nice POSIX emulation layer that Cygwin provides.

Actually, I'm surprised that everyone seems to be ignoring that Winsock uses standard BSD functions + proprietary extensions.

In fact, except for the mandatory WSAStartup() call required in Windows. Programs built using standard Unix sockets _should_ compile in Windows.

Does any one know how to do it in C++ if so could you send me the code at Raycar427@msn.com, and if it needs a certain type of header file could you send that also?... thnx, you can also put it on the forum, i bet many ppl would be happy about that. hmmm...god can i have another cheese sandwich?

lol... here's Beej's guide [if you dont feel like googling :P] http://www.ecst.csuchico.edu/~beej/guide/net/

MrSmiley, Have you considered using SDL? SDL is a nice library for making games and other kinds of programs. It has a very helpful module for network programming, SDL_net.

As for making a LAN game, you need to decide if the game will only work on a LAN, or if it will work on the Internet too. For LAN-only games, you can use the UDP protocol to send packets to the LAN's broadcast address. This is the easiest method. For Internet games, your program must send packets to all of the players in the game. The type of game you are making will determine which method you should use. Network game design is a big topic. We can't say anything else until we have some details about your project.

I'm afraid it's not true. Although Winsock provides functions with similar names and behavior to the BSD sockets, they are not compatible. For example, Winsock does not let you read() on a socket; you must use recv() instead. Also, Winsock's flags have completely different names. Even though the two APIs are not compatible, it is usually not difficult to port a BSD sockets program to Winsock.

Thank you for correcting Mike_L. I actually never did socket programming in *NIX so I didn't know the differences. I just 'guessed' they were very similar.
