💖 tiocgpgrp(9) 💖

okay so welcome to the Kernel API Manual, bestie! this page is about tiocgpgrp, and it's literally here to get a process group. no cap. 🫶

✨ NAME ✨

tiocgpgrp — get process group

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

• tty — the tty passed by user. yes bestie, user brought it.
• real_tty — the tty side of the tty passed by the user if a pty else the tty.
• p — returned pid.

💅 DESCRIPTION 💅

so this one obtains the process group of the tty. if there is no process group, it returns an error — not a vibe, but that's the deal. 😭

Locking: none. Reference to current->signal->tty is safe. slay, no locking drama. ✨
