And what I pointed out was simply another choice. Whether he implements
the solution in software or takes the administrative route is obviously
his choice. And if

You could try kvm_getprocs with an argument of KERN_PROC_UID.

Hello,
can anyone give an idea of C code on how to quickly count
the number of processes for a given user? I want to patch
Apache in order to prevent it from forking new process
over user's maxproc limit (while running suexec).
Should I look at ps(1) source code or there are some
other examples?

Hey.
For example i cantrol fchflags syscall via my kernel module.
I got:
int
n_fchflags(register struct proc *p, register struct fchflags_args)
{
...
}
struct fchflags_args {
int fd;
int flags;
};
I can get vnode of changed file.
I can get inode number of changed file.

I wrote a simple program which does this:
gettimeofday
something (takes several seconds)
gettimeofday
print time elapsed
Several runs of the program take about the same time but the time
changes wildly when the executable is called differently.
