Hello,
I'm writing a kernel module, and it involves traversing the proc list searching for
the right structure,
however, when I use SLIST_NEXT(p, p_list) in the program, I get a warning when I
compile it:
warning: statement with mo effect
What am I doing wrong? I've read the manpages on queue and looked at the proc
structure.
Here's the code:
int
prfw_setflags(p, uap)
struct proc *p;
struct prfw_setflags_args *uap;
{
...
if (uap->id) {
while (uap->id != p->p_pid)
LIST_NEXT(p, p_list);
}
...
}
Thanks a lot.
