tty_line_name(9)

💖 tty_line_name(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're in kernel land today, and no, it's not scary, i promise 🫶 this one's a lil cutie and honestly kind of a slay.

---

✨ NAME ✨

tty_line_name — generate name for a tty 🎀

---

🌸 SYNOPSIS 🌸

ssize_t tty_line_name (struct tty_driver *driver , int index , char *p
);

like, that's the whole signature, that's it, that's the girl 💅

---

🦋 ARGUMENTS 🦋

• driver — the tty driver in use, aka the driver you're working with, she's the main character here 👑
• index — the minor number, yep literally just the minor number 🧚
• p — output buffer of at least 7 bytes ⚠️ okay bestie listen, at least 7 bytes, do not be out here handing her a tiny buffer, she will not be okay with that

---

🌈 DESCRIPTION 🌈

So the whole vibe: you hand it a driver reference, it generates a name from that reference, and it writes that name into the output buffer p. Simple, clean, iconic, ate ✨

Locking: None 🔓 — no locks, no drama, nothing to worry about on that front, fr fr.

and that's the whole page bestie, go forth and name some ttys 💅✨

🎀 cute lil sign-off: this icon came to you from the source dir ./drivers/tty, dated October 2026, and she lives at tty_line_name(9) in the Kernel API Manual. mwah 💖
