tty_get_icount(9)

✨ NAME ✨

tty_get_icount — get tty statistics. Also hi bestie, you’re on the tty_get_icount(9) page from the Kernel API Manual 🫶.

🌸 SYNOPSIS 🌸

int tty_get_icount (struct tty_struct *tty , struct serial_icounter_struct *icount );

🎀 ARGUMENTS 🎀

• tty — tty device. The terminal-ish main character.
• icount — output parameter. This is where the stats copy goes, iykyk.

💖 DESCRIPTION 💖

Okay so this function gets a copy of the tty’s icount statistics. That’s the vibe — no cap.

Locking: none (up to the driver). Literally none from this side; the driver has to handle its own business.
