I found a HAS_SEMAPHORE flag in the mmap man pages and as the man pages lacks some explanantion I check in the source code but I have been unable to find anything on this flags what is it supposed to do ? is it implemented in FreeBSD ? Is there somewhere a tutorial that explain in depth the use of these system calls ? Thanks for your help, ---------------------------------------------------------------------------- Didier Derny didier@aida.remcomp.fr ----------------------------------------------------------------------------
