pthreads means POSIX threads. POSIX is a standard which means that POSIX threads, among many other things, work the same way across many different UNIX and UNIX-like systems.

For the third time, I'd suggest simplifying the problem before you even begin to think about concurrency. Don't build a chat server, build a communication library. Build sets of tiny, tiny example programs; one pair where the server sends and the client recieves, another where the client sends and the server recieves, another where the client connects to what you name instead of anything builtin, etc. These don't have to be interactive, so you don't have to worry about user input and network input at the same time; you can get them working without worrying about threads. Once you perfect sending, recieving, and connecting, then you can put the puzzle pieces together in a multithreaded application.

I understand the temptation to skip all that and build a simple something without any framework, but when you get into it, these "simple" things inevitably become way more complicated than they first appear. If you don't break it down, you won't be able to understand what you've written after leaving it for a week.

gvrng

NAME

       gvrng - An interactive, introductory programming language.

SYNTAX

       gvrng [world file | program file]

DESCRIPTION

       Guido van Robot is a project developed by advanced high school students for use by their peers as a learning tool and precursor to the fur-
       ther study of programming with Python. It is a minimalistic programming language providing just enough syntax to help  students	learn  the
       concepts  of  sequencing, conditional branching, looping and procedural abstraction. It's biggest strength is that it permits this learning
       in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is  an	interactive,  introductory
       programming  language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all,
       it's a whole lot of fun, too!

       At this point, you are probably asking yourself, "What is GvRng, specifically?" The gist of it is that it is a robot represented by a  tri-
       angle  on  the screen that moves around in a world made up of streets and avenues, walls and "beepers", which Guido can collect or set. His
       actions are completely guided by a program written by the user.
