>Hi all, I have setup, by means of register_ctl_table() call, some entries
in
>/proc/sys filesystem, and I can read and write to these entries with no

>The problem is that I cannot find the way to read/write from inside a user
>space apps, using the sysctl() call. I can read the other /proc/sys/kernel,
>/proc/sys/net, /proc/sys/vm, but I cannot find my table. Maybe because this
>table has been defined someway dinamically (that is I did not modify the
>sysctl.h files adding my CTL_VAR defines).
