What are you intending to do? In fairness, who cares? It is a basic and reasonable thing to do. I did it only last night: I wanted to know if stderr was a tty or pipe, versus a regular file, as I wanted to special case some error formatting (loosely speaking, default automatic people-friendliness versus log file verbosity). I know that why people want to do things is important, as they may be choosing the wrong approach. But the above question seems very simple and very basic: he seems unable to get the OS file descriptor number from the standard streams, and this is surprising. I think he even started the thead with almost a transcript of the failure, and backed off the the above abstraction when someone complained.
