Hi,
I m a newbie to linux. Can someone help me on how to Create a module that uses the /proc file system to return a list of all pids and ppids for processes om the system . I googled and found the following:

#include < linux/kernel.h >
#include < linux/sched.h >
#include < linux/module.h >

int init_module(void)
{
struct task_struct *task;
for_each_process(task)
{
printk("%s [%d]\n",task->comm , task->pid);
}

return 0;
}

void cleanup_module(void)
{
printk(KERN_INFO "Cleaning Up.\n");
}

But I need to read pids, ppids from the /proc file and not from the module
Can someone help me with this. Thanks in advance.

Hi

This ps works by reading the virtual files in /proc.

from

UNIX man pages : ps ()

You can also refer to your ps man page.

Hope it helped
