thanks i tried getloadavg() it worked.
but when i tried to put it in the kernel the kernel
failed to link.
i also looked at sysctl(3) and i guess it is also for
user
based programs.
so i looked at the sys/sysctl.h and found that there
was
sysctl_find_oid() that was defined for kernel. but i
don't
know how to use it. i could not get any info on the
web.
the function declaration was ::
int sysctl_find_oid(int *name, u_int namelen, struct
sysctl_oid **noid,
int *nindx, struct sysctl_req *req);
isn't it the function i should be using to retrieve
the sysctl
value ???
how should i use it ??
any demo on using it would be immensely helpful for
me.
thanks,
kamal
