  34.           The VkInput class is an object-oriented interface to Unix pipes.  It
  35.           sets up a pipe, using the VkInput class to provide callbacks to the
  36.           application when input is available.

  46.           Create a non-blocking pipe, setting fd to the write end.  The read
  47.           end is attached to the VkInput object, and the VkPipe::inputCallback
  48.           callback is called when input is available.
