Yes, you are completely correct. And 'designed' was perhaps a poor word choice. In terms of wrappers of POSIX, I'm definitely not saying that POSIX is dead and not used. It's great that it is a beginning point for porting to various platforms. What I was more pointing out is that as a developer, its your stdlib's portability that is key. For example, many languages use POSIX interfaces where they can, and then switch to platform specific interfaces where necessary, for performance or other reasons.
