Looking for information about TCP connections

[Airslash]

Hello,

me and 2 fellow students are busy working on our endterm project at school. The assignment consists of a cross platform multimedia application (a game in our project) that can be compiled on Windows, Linux or Apple.

We have extended our client to have online capababilities, but I'm having trouble finding decent information about making cross platform TCP or UDP connections to a server. I know there is SDL_NET to use as it's a good cross platform library, but I was hoping someone knows a good online resource regarding the creation of UDP/TCP connections. I know the word socket comes to mind, but this is always platform specific...

So I hope someone can provide a good resource site where they explain sockets for each platform so that we are able to create our own little lib to send text messages to the server.

Mostly you endp up with problems if you use OS specific socket calls.
like using winsock calls and using it on Linux.
But if you want to make cross platform tcp connection you should use AF_INET protocol family and try to use only generic calls instead of OS specific calls.
Following calls works on windows/linux
socket()
bind()
listen()
accept()
read()
write()
select()
shutdown()
close()

Hope this helps you

Definitly, just wondering if specific headers are required to perform these calls, or they all have to be defined from scratch. I mean is there a base class I can work with in C++ and write a sort of wrapper around it, or do I need to make it all from scratch ?

A couple come to mind, have a look at C++ Sockets (lightweight), or ACE (heavyweight).
