tiocspgrp(9)

✨ NAME ✨

tiocspgrp — attempt to set process group. That’s the whole vibe: it attempts to set the process group, bestie 💅

🎀 SYNOPSIS 🎀

int tiocspgrp (struct tty_struct *tty , struct tty_struct *real_tty , pid_t __user * p );

🌸 ARGUMENTS 🌸

• tty — the tty that got passed by user. User brought it, we’re looking at it 👀
• real_tty — the tty side device that matches the tty passed by user. Matching set, slay ✨
• p — pid pointer. Literally just a pointer to a pid 🫶

💅 DESCRIPTION 💅

okay so the whole plot: this sets the process group of the tty to the session passed. Only permitted where the tty session is our session — like, main character session only, periodt 👑

Locking: RCU, ctrl lock. Those are the locking girlies, no cap 🔒
