[C] automatically logout users

noir911 · 06-26-2008, 10:38 PM

I am learning C and want to write a program that would kick out users if they are idle for more than "x" minutes.

Could anyone tell me what functions do I need to write this program?

pseudocode:

Code:

main () {
   set timer or sleep n
   if timer expired
      kill process id of user's shell
}

The system or library calls you'll want to expore: kill(2), sleep(3). There are others for more control.

Or I have to write for u?

How can a student learn if you give the answer? The learning comes from working out the details, exploring, and discovery. Don't take away that opportunity.

Embed shell script into the code.
That's what system("command") is there for.
Now don't ask for any more detail than that!
