Is that faster/slower than ioctl()s, or just cleaner. just FYI, i may have phrased it overly strongly that ioctl's were on their way out -- there's obviously a lot of them still in the kernel, but just as obviously, they're considered old school, as you can read here in this article from way back in 2001. http://lwn.net/2001/0524/kernel.php3 i doubt they'll ever *truly* go away, but there are obviously better alternatives these days with /proc and /sys. rday -- ======================================================================== Robert P.
