Would probably make sense to check if the operation succeeded instead of silently handling the error.
What about changing this to something like:
let size = readlink("/proc/self/fd/\(descriptor)", pointer, filename.capacity)
if size == -1 {
fatalError("readLink failed, errno: \(errno)")
}There was a problem hiding this comment.
That's better. But fatalError? Do you think it's OK here?
