I don’t personally agree with that judgement. While the failure condition is at the OS level it’s still affecting the function of the program an in unexpected way.

Plus the whole point of STDOUT is that it is a file. So it shouldn’t change the developers mental model if that file happens to be a pseudo TTY, a pipe or a traditional persistent file system object. This flexibility is one of the core principles of UNIX and it’s what makes the POSIX command line as flexible as it is.

With that in mind, is this criticism of the Java hello world valid? Its output abstracts more than stdout and maybe in Windows this but would not occur. (I don't know, just discussing)
