Vetting the cargo

Vetting the cargo

At some point someone determined that it might have security problems and was potentially not threadsafe. So it was depreciated from the POSIX standard. The last time I looked into it there was some message that said people could trivially write their own version if they needed the functionality. How trivial is writing something that requires a reasonably deep understanding of things like terminal attributes?

Yeah, this seems exactly backward to me. If a reasonably common function has potential security and thread safety problems, that's a sign that it probably should be handled by a library everyone has access to. If the standard implementation has problems, it's extremely likely all those hand-rolled solutions that replace it will have the same kinds of problems, but with many fewer people around to notice and fix them. Things that are common but fiddly are exactly what you're supposed to put into libraries, so it gets written carefully exactly once.
