Programmatically capture screenshots in OSX

Question

I am going to port some screen capturing (C ++) code for linux to osx. The current solution runs graphical applications in xvfb and then uses xlib to capture screenshots from the screen. (This will also support if we work without xvfb).

So, as I understand it, osx moves aside from X11, so my question is what to use besides xlib to implement it now? I found Quartz Display Services . Is that what it makes sense to use now? Will this work with xvfb?

Yes, you can call functions such as CGDisplayCreateImage(documentation related to you), linking the application infrastructure with your C ++ tool.
