alloc_tty_struct(9)

🎀 alloc_tty_struct(9) 🎀

okay so this is a page straight out of the Kernel API Manual (yes, the kernel girlies have their own manual, we stay educated 💅), and it's about alloc_tty_struct — literally the glow-up ritual where a brand-new tty gets born. periodt.

---

✨ NAME ✨

alloc_tty_struct — allocate a new tty 🍼

---

🌸 SYNOPSIS 🌸

struct tty_struct * alloc_tty_struct (struct tty_driver *driver , int idx );

that's it, that's the whole signature bestie 🫶

---

🦋 ARGUMENTS 🦋

• driver — the driver that's gonna be handling the tty we hand back. it's giving "the adult in the room" energy 👑
• idx — the minor of the tty, iykyk 🔢

---

💖 DESCRIPTION 💖

okay so this subroutine allocates and initializes a tty structure. brand new, fresh out the box, main character energy ✨

Locking: none — because the tty in question is not exposed at this point 🙈 nobody can even see it yet, so there's nothing to lock. we love a private era.

not me stressing over locking when there's literally no locking to stress about 😭 slay.

🌈 SEE ALSO 🌈

the full squad, in order, no skipping, we don't do that here 💅
