I tried searching for kernel level mutex but couldn't find any information on the same. The kernel level mutex functions mtx_lock(..), mutex(..), mtx_init(..) and other mtx_ functions are available from FreeBSD 5.0 onwards and not in FreeBSD 4.8. Kindly adavice me how should i proceed. Also is there anything like Gaint lock in FreeBSD 4.8. If so then how can i use it. Any early reply will be of great help. Thanks in advance Jitendra --------------------------------- Do you Yahoo!?
