tty_buffer_set_limit(9)

💖 tty_buffer_set_limit(9) — NAME 💖

okay so welcome to tty_buffer_set_limit(9) from the Kernel API Manual, bestie 💅 this page is literally about one little function with main character energy.

tty_buffer_set_limit — change the tty buffer memory limit. periodt.

---

✨ SYNOPSIS ✨

here's the exact fit, no edits, no cap:

int tty_buffer_set_limit (struct tty_port *port , int limit );

---

🎀 ARGUMENTS 🎀

• port — the tty port you're changing 🫶
• limit — the memory limit you're setting ✨

---

💅 DESCRIPTION 💅

This changes the tty buffer memory limit. iconic behavior, honestly.

⚠️ and bestie, this part is a must: it must be called before the other tty buffer functions are used. no cap, that's the vibe check.
