macOS how to make a connection between Macs

[Howiieque]

I want to write an app send text between two macs like the msn do. I just want to learn how to do so and learn something about network. what should i learn to implement this task? and which classes can facilitate things?
and what if connect to a windows?

I wrote soemthing exactly like this just last year in one of my programming classes. I'd look into C with emphasis on pipes

 

[Howiieque]

could you give a little more hints, about pipe?
and it seems that socket can do this thing, is there another option?

Cocoa distributed objects is also a nice way to do this.

Thank you.

Yeah, there are two ways to do this:

BSD Sockets
Cocoa Distributed Objects

Either one will work. If you intend to make this app multi-platform in the future (Beyond iPhone and Mac), then I'd look into BSD Sockets. Otherwise distributed objects should be just fine.

Java's the easiest way to go. Give Java sockets a try.

Thank you for given all the information.
Sockets and distributed object are both what i want to learn, although i just heard of them and don't know what they exactly are.
And then i want to Windows join in by using Java.

Yup, look at sockets.

It will require more work on your part, but the code will be more portable. The same basic concepts will apply on any Unix-like system, Windows, Java, OS X, and so on.

It will also give you a bit more fine control over the data sent.
