Now, I can find the corresponding code about 'ioctl' routine. But, I could not find any code about 'sysctl', why? how the FreeBSD realize the corresponding functions?

Hi guys,
&n= bsp; In the "TCP/IP Illustrated, Volume2: The Implementation" book,
th= ere give 'ioctl' and 'sysctl' in the kernel routine.
ioctl ->= ; sooioctl->(interface)ifioctl.....
sysctl-> net_sysctl -= > pr_sysctl -> ip_sysctl....
Now, I can find the correspo= nding code about 'ioctl' routine.
But, I could not find any code about= 'sysctl', why?
how the FreeBSD realize the corresponding functions?

Thank you!

Best Regards
Ouyang Kai=
