tiocgsid(9)

✨ NAME ✨

okay bestie, this is tiocgsid(9) from the Kernel API Manual — the function whose whole entire job is get session id. no cap, that’s the vibe. 💅

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

• tty — the tty passed by user. yes, the one the user handed over.
• real_tty — the tty side of the tty passed by the user if it’s a pty; otherwise it’s just the tty. 🦋
• p — pointer to returned session id. like, the spot where the returned session id goes.

🦋 DESCRIPTION 🦋

This one obtains the session id of the tty. If there is no session, it returns an error — periodt. That’s the whole plot, bestie; no extra lore needed. 💖
