I'm working on porting an OpenGL software package to the Mac (and maybe Linux in the future). The software currently runs on Windows, but it was written to support multiple platforms. There is a library that contains some OS abstraction classes, such as threads, shared memory, mutex, timer, keyboard input, mouse input...

My question is where to find a description of the BSD Api's that I should use in the abstraction layer?

Second question. Could someone give me an example (or point me in the right direction) on how to programically create a window. I know that Project Builder/Interface Builder allow for easy building of GUI's, but I would like to build a simple window with an OpenGL context without the use of a nib file.

Thank you

As far as threads, you'll want to look into pthreads. This would also cover your Linux version.

As far as NOT using a nib file... well, why?? It's much easier to build a user interface and make the connections by hand than it is to do it in code. You're looking at comparing something that may take a few minutes at the most with something that could take days to figure out. Why do it the hard way?

Anyway, there are ways to do that with the GLUT library. It's cross platform. That might be what you need to look into.

The reason that I wanted to create the window without the nib file is that the Windows version has a generic create window method. You pass it a set of arguements and it creates a window or full screen OpenGL context. From that point on all the action is within the window. I don't want to make a complete app by hand, just a single window.

I hope this makes sense.

There is a tutorial at cocoa dev central that does what I think you need.
