#ioctl(path, cmd, arg, fuse_file_info, flags, data) ⇒ Object

  • path (String)
  • cmd (Integer)
  • arg (FFI::Pointer)
  • fuse_file_info (FuseFileInfo)
  • flags (Array<Symbol>) —
    • :compat 32bit compat ioctl on 64bit machine
    • :unrestricted not restricted to well-formed ioctls, retry allowed (lowlevel fuse)
    • :retry retry with new iovecs (lowlevel fuse)
    • :dir is a directory file handle
