n_tty_open(9)

✨ n_tty_open — open an ldisc ✨

okay bestie, welcome to the n_tty_open(9) page 💖 this is a Kernel API Manual situation, and honestly? it's short but it matters. let's get into it 🎀

🌸 SYNOPSIS 🌸

int n_tty_open (struct tty_struct *tty );

💅 ARGUMENTS 💅

• tty — the terminal you're opening, bestie. that's it. that's the whole argument 🫶

✨ DESCRIPTION ✨

so like, n_tty_open gets called when this line discipline is being attached to the terminal device. that's the moment, the main character entrance, the whole vibe check 👑

it can sleep 😴 (yes, fr, it's allowed, don't panic). and it's called serialized — meaning no other events will occur in parallel, so nobody's cutting in on your moment, no cap. and also? no further open will occur until a close 💀 so like, one at a time, periodt.

ngl this one is short but iconic. the way that it just attaches and sleeps and holds the line until close 😭
