A little too late since I already hacked the source for sysctl(8) and figured out how it works. Here's what I have: mib[0] = 0; Unused according to sys/sysctl.h. So, 0,1 - get name from oid. 0,2 - get first sysctl node/leaf? (I haven't used this one yet) 0,3 - get oid from name. 0,4 - get format for oid? (I haven't used this one yet either) At least that's that I have. I wrote a program based on that and it does work, quite well in fact. I am not concerned about portability since the software that I'm writing will run ONLY on FreeBSD and maybe some of the variants. -- Daniel Rudy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
