It returns 1 if the stream is not full (so that we can continue send
something), otherwise 0.

Generally, it's used like:

  if (qemu_file_rate_limit(f)) {
      /* we can still send something to the stream since it's not full */
  } else {
      /*
       * either the stream is broken, or we have already sent enough
       * data, so that it's reaching the limit we set via
       * qemu_file_set_rate_limit(). We should not send anything now.
       */
  }

And I would suggest avoid sending the same topic in two days. :)
