If you mean exchanging data in general between userland and kernel then rummaging though the source looking for sysctlbyname() (or sysctl() or sysctlnametomib()) will turn up lots of hits. Without knowing exactly what you are trying to achieve, I can't be absolutely certain but potentially interesting places to look would be conscontrol(8), dumpon(8), ipcs(1) etc. Note that most of the *stat commands, as well as ps, use sysctl rather than grovelling around in /dev/kmem. -- Peter Jeremy
