pty_line_name(9)

💖 pty_line_name(9) — Kernel API Manual 💖

okay bestie, welcome to the pty_line_name page from the Kernel API Manual — yes, the manual name is "Kernel API Manual", and this whole page is about one tiny iconic little function that names your ptys. it's short, it's sweet, it's giving side-quest energy. let's go 🫶

---

✨ NAME ✨

pty_line_name — generate name for a pty 🎀

---

🌸 SYNOPSIS 🌸

void pty_line_name (struct tty_driver *driver , int index , char *p );

like, that's the whole signature. no cap. 💅

---

🦋 ARGUMENTS 🦋

• driver — the tty driver in use, aka the one doing the work here 👑
• index — the minor number. that's the number, bestie, the minor one 🔢
• p — output buffer of at least 6 bytes. at least six. six is the floor, don't come at it with five 🙈

---

⭐ DESCRIPTION ⭐

so what does it do? it generates a name from a driver reference and writes it to the output buffer p. that's it. that's the whole vibe. it's a name-generator for ptys and it slays at exactly that one job ✨

Locking: None. no locks, none, zero, nada — it's just out here living its life 💀
