Does this method do set the parameters at load time or after load ? Cause Linux can insmod abc.o param=123; param is set to 123 when abc is linked to the kernel. Could u please give me a simple example? thanks very much! CcM, a newbie.

I think kernel tunables (set in /boot/loader.conf at boot time or via /bin/kenv at runtime, readable in-kernel via TUNABLE_* macros) are your best bet here. -- Dan Nelson dnelson@allantgroup.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" --------------------------------- Do You Yahoo!? 注册世界一流品质的雅虎免费电邮
