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.
