They aren’t - I didn’t remember fnctl() was varidadic. I shall quote an Apple engineer then ..
"This is not possible in Swift. C variadics are inherently unsafe, and not compatible with Swift variadics. You're encouraged to provide alternate versions of your collection-y variadics that take an array. Your format-y variadics (like this one?) can use Swift's String's variadic initializers ahead of time."
So you get to go wrap fcntl() in something else it seems.
