tiocsetd(9)

🌸 NAME 🌸

okay bestie, this is the tiocsetd(9) page from the Kernel API Manual — manual name folded in near the top, we're so fancy. tiocsetd — set line discipline. That's the whole name, and it ate. 💅

✨ SYNOPSIS ✨

int tiocsetd (struct tty_struct *tty , int __user *p );

💖 ARGUMENTS 💖

• tty — tty device. iconic little device, no notes.
• p — pointer to user data. yes ma'am, pointing at user data.

🦋 DESCRIPTION 🦋

It sets the line discipline according to user request. Like, user asks, it sets the line discipline — main character behavior honestly. ✨

Locking: see tty_set_ldisc; this function is just a helper. No cap, it is not doing the heavy lifting alone. 🫶
