tty_buffer_init(9)

💅 tty_buffer_init(9) — from the Kernel API Manual, bestie

okay so we're literally in the kernel API manual right now, and this page is about tty_buffer_init — yes that's the function name, and yes the manual section is 9. stay with me, this one's short and slay.

✨ NAME ✨

tty_buffer_init — prepare a tty buffer structure 🎀

---

🌸 SYNOPSIS 🌸

void tty_buffer_init (struct tty_port *port );

that's it. that's the whole signature. no return value, it's giving void and unbothered 💅

---

🦋 ARGUMENTS 🦋

• port — the tty port to initialise. that's the one you're setting up, bestie 🫶

---

💖 DESCRIPTION 💖

so what this does is set up the initial state of the buffer management for a tty device. like, the very first vibe check for the buffers — before anything else buffer-related gets to happen ✨

highkey important: this must be called before the other tty buffer functions are used. not optional. not "whenever you get around to it." before. periodt 🔥
