tty_ldisc_deinit(9)

💖 tty_ldisc_deinit(9) 💖

okay bestie, welcome to the Kernel API Manual — yes, we’re doing tty kernel lore today and it’s lowkey iconic. this one is short but important, so let’s get into it fr fr. 💅✨

🎀 NAME 🎀

• tty_ldisc_deinit — ldisc cleanup for new tty. literally the cleanup era for a fresh tty, no cap. 🦋

✨ SYNOPSIS ✨

void tty_ldisc_deinit (struct tty_struct *tty );

🌸 ARGUMENTS 🌸

• tty — the tty that was allocated recently. like, brand-new-recently, not been around the block yet. 🫶

💖 DESCRIPTION 💖

The tty structure must not be completely set up (tty_ldisc_setup) when this call is made. that’s the whole vibe check, bestie: this call happens while tty is still not completely set up. periodt. 😭

no cap — keep that caveat in mind: tty_ldisc_setup must not have fully set up the tty structure yet when you call this. 💀
