Hi!
I want to write a function whose behaviour should be similar to kill system call i.e=> I have to send the signal to the given process. Is it possible to do it by over writting pending signals field in the stat file for the corresponding process in the proc directory? I got this thought, i dont think its possible because Its( /proc/pid/stat ) permissions are set to 0444, even as a super user i cant change permissions.

Is there any other way of implementing the kill system call functionality in user space. Or any other way to change the stat file ?
Please give me some idea to solve this problem. I will be very thankfull to you.
Bye,

No. And frankly I cannot imagine why somone would want to do that...

I gues it is possible.
Try to dissamble shutdown or halt.That shutsdown your system(changes the level).
Good luck.

It would require a kernel bug for this to be possible.
I would check the sources instead: much easier reading. It's open source after all...
But don't bother, "shutdown" uses the kill() system call.

I don't understand why you would want to do this. If kill() does what you want, then why reinvent the wheel? If you want to do something that kill() doesn't do, what would you want to do differently?
