You could probably try to write something really generic which wraps fcntl() using an UnsafeMutablePtr<UInt8> as a final argument and then massaging stuff in Swift to poke it over and back, but that really would be a horror. You’re probably better off just shimming the actual operations you really actually need into a set of specialized c calls, each one should take 2-3 lines of code only for that.
That's what I ended up doing (setNonblocking(int inFileDescriptor)), but, I was asking for the sake of learning the language. It would be nice to have generic replacements for fcntl() and ioctl().
