    Look at your monitor. Technically this is an output device.
    But there are little controls, where you can make adjustments.

    ioctl is nothing else: A controller for an io-stream.

    It also makes quite clear, that we are packetizing read/writes now.
    And it cannot be fdopen()ed ;-)

    Maybe we COULD split strictly for reads and writes, but
    we still need a side channel for that to be opened by
    passing a file descriptor.

    How else would you control a tty/pty which you got as stdin/stdout?

    Maybe one could hack this into xattr-support? ;-)
