Hi,
I'm trying to list all of the tasks and their
children. (Im using a 2.6.5-7 kernel)
The code below does not list all of the pids as
compared to the /proc entries.
Why does the following code not list all of the
active pids in the system?
please cc this id.
-----------------------
void list_pids(void)
{
struct task_struct *tp;
struct list_head *_p;
struct list_head *_n;
struct task_struct *p;
read_lock(&tasklist_lock);
for (tp = &init_task; (tp = next_task(tp)) !=
&init_task; ) {
printk("[parent] pid =%d \n" ,tp->pid );
list_for_each_safe(_p,_n, &tp->children ){
p = list_entry(_p,struct
task_struct,sibling);
printk(" [child] pid =%d \n", p->pid
);
}
}
read_unlock(&tasklist_lock);
return ;
}
