Pretty much. You need to create a handle, connect it to something and perform transactions on it. Some of those must be serialized and they have both input and output data, so they don't fit sysfs and friends. It's effectively mostly a message passing system - the closest other interface is the socket one but it doesn't really fit that and I don't think Dave wants 'its got a connect sort of op so lets make it a socket family' to be the device norm ! The identifier for the object is also long so doesn't work for a set of devices by minor number either. I think the more useful step is going to be some example user space as that above all will show how it is intended to work Alan _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
