send_break(9)

💥 send_break(9) 💥

okay bestie, you're in the Kernel API Manual and this page is all about send_break(9) 💖 it's giving “tiny timed-break helper with main character energy,” and yes, the locking note is part of the vibe.

🌸 NAME 🌸

send_break — performed time break

✨ SYNOPSIS ✨

int send_break (struct file *file , struct tty_struct *tty , unsigned
       int duration );

🎀 ARGUMENTS 🎀

• file — file object. literally the file object in question, bestie.
• tty — device to break on. this is the tty getting the break treatment.
• duration — timeout in mS. keep that unit exactly as written, no cap.

🦋 DESCRIPTION 🦋

okay so send_break() performs a timed break on hardware that lacks its own driver level timed break functionality. that's the whole assignment. slay ✨

Locking: tty->atomic_write_lock serializes. that's the lock note, and it is doing exactly what it says on the tin 💅

okay that's the whole page, bestie. this masterpiece is served from ./drivers/tty, dated October 2026, and it's still send_break(9) in the corner like main character energy 👑💅
