No, they do not "change size depending on platform and endianess" if basic rules are observed. Defining compatible ioctls is not rocket science. Sure, "int" should not be used in ioctl arguments or other binary interfaces. (I never said EVIOCSKEYCODE was not lacking, I only said it exists already. When you talk about better scancode-to-keycode converter configuration, then you are talking about EVIOCSKEYCODE, not about LIRC or a hypothetic replacement of LIRC. Ergo, the decision about whether to merge LIRC or not is not blocked by this configuration interface issue.) > Also, how do you create the devices for each remote?
