adding proc to allproc

[Ferner Cilloniz]

Hello everyone.

I am playing with freebsd and just learning some things about the
FreeBSD kernel. 

So for my first quest i am placing random processes from the allproc
list into a list of my own and trying to add them back into allproc

I have pasted the code below.

-----------------------------------------------------------------------
struct proc *p = a process from my own list;
if( p != NULL && (p->p_state == PRS_NEW || p->p_state == PRS_NORMAL) ){
       LIST_INSERT_HEAD(&allproc, p, p_list);
}
-----------------------------------------------------------------------

Thanks.
