Now for transffering data from user to kernel space can be done through existing straight 3-ways which I AFAIR: 1) ioctl (they are single directional and can be used to pass buffers, but user fucntions will call ioctl) 2) sysfs (that is a better replacement for adding new ioctls in driver, just for user/kernel interaction) 3) netlink sockets (these are for bi-directional kernel/user communication, means kernel can also send data to user space rather always user space have to ask for data as it is with the above 2 cases) -- Fawad Lateef - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
