anyone know what a "lockless ioctl" is?
reading a course outline and there's a reference to "lockless ioctls". no idea what that is, and google doesn't make it any clearer: http://www.google.ca/#hl=en&sclient=psy-ab&q=%22lockless+ioctl%22&oq=%22lock... did such a thing ever exist? rday -- ======================================================================== Robert P.
