tty_ldisc_failto(9)

💅 tty_ldisc_failto 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is tty_ldisc_failto(9), and honestly? she's a little rescue worker and she ate. 🫶

---

🌸 NAME 🌸

tty_ldisc_failto — the helper for ldisc failback 🎀

(that's it. that's the whole name section. short, sweet, iconic.)

---

⭐ SYNOPSIS ⭐

int tty_ldisc_failto (struct tty_struct *tty , int ld );

literally just vibes and a return type, no cap 💀

---

🦋 ARGUMENTS 🦋

• tty — the tty we're gonna open the ldisc on 🖥️✨
• ld — the ldisc we are trying to fail back to, i.e. the safe place we're running home to 😭💖

---

👑 DESCRIPTION 👑

okay so picture this: you're a tty, you tried to switch ldiscs, it did NOT go well, and now you're sitting there with nothing attached which is lowkey terrifying 🙈. This helper's whole job is to try and recover a tty when switching back to the old ldisc fails and we need something attached. She's the friend who shows up with a hoodie and a snack when your night goes sideways fr fr 🧚💜

not me being obsessed with a recovery function but here we are 💅
