gsmld_open(9)

💅 gsmld_open — like, the manual page, bestie

okay so this is gsmld_open(9) from the Kernel API Manual and honestly it's a whole vibe — it's the function that opens an ldisc. That's the tldr, but stay with me because there's actual substance here 🫶

✨ NAME ✨

gsmld_open — open an ldisc ✨

🌸 SYNOPSIS 🌸

int gsmld_open (struct tty_struct *tty );

🎀 ARGUMENTS 🎀

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

🦋 DESCRIPTION 🦋

So like. This bad boy gets called when this line discipline is being attached to the terminal device. main character energy fr fr 👑

It can sleep 😴 — no cap, that's a real thing you have to know, she naps.

It's called serialized, which means no other events will occur in parallel. none. zero. nobody's cutting in on her dance floor 💀

And no further open will occur until a close. periodt. that's the rule 🎯

👑 SEE ALSO 👑
