Yes. This is an extremely basic question, you may wish to grab a book or two on linux kernel programming. The kernel is in a different address space than user code, so you can't use direct calls. Write a syscall, an ioctl, a driver, or create /proc entries. - Dan -- Dan Kegel http://www.kegel.com http://counter.li.org/cgi-bin/runscript/display-person.cgi?user=78045 ** Sent via the linuxppc-embedded mail list.
