tty_ldisc_reinit(9)

✨ NAME ✨

okay so welcome to the Kernel API Manual, bestie — this page is highkey all about tty_ldisc_reinit, aka reinitialise the tty ldisc, and it's literally the “close the old instance, open a new one” reset moment for your line discipline 💅✨

🌸 SYNOPSIS 🌸

int tty_ldisc_reinit (struct tty_struct *tty , int disc );

🎀 ARGUMENTS 🎀

• tty — the tty to reinit, periodt. That's the one getting the glow-up 🫶
• disc — the line discipline to reinitialize. Yes, that exact one, bestie.

💖 DESCRIPTION 💖

The way this function completely reinitializes the line discipline state? Obsessed. It closes the current instance — if there is one — and opens a new instance, fr fr. Main character energy, ngl ✨

If an error occurs opening the new non-N_TTY instance, that instance is dropped and tty->ldisc gets reset to NULL. The caller can then retry with N_TTY instead, iykyk 😭💅

🔥 RETURN 🔥

• 0 if successful — slay ✅
• otherwise, an error code < 0 — not slay, but at least you know 💀
