tty_port_carrier_raised(9)

📦 version 7.3.1, in nixpkgs unstable

💖 tty_port_carrier_raised(9) 💖

okay so first things first, bestie: this page lives in the Kernel API Manual, and the function we're stanning is literally called tty_port_carrier_raised. yes it's a mouthful. no we don't make the rules. 🎀

✨ NAME ✨

tty_port_carrier_raised — the carrier raised check, aka "is the line actually up, or are we just pretending" 💅

🌸 SYNOPSIS 🌸

bool tty_port_carrier_raised (struct tty_port *port );

that's it. that's the whole summoning ritual. she's a bool, she takes one pointer, she does one job. main character energy fr fr ✨

🦋 ARGUMENTS 🦋

  • port — the tty port in question 🫶 like, the actual struct tty_port * you're asking about. that's the whole argument list. one (1) port. iconic, honestly.

💜 DESCRIPTION 💜

so this is a wrapper for the carrier detect logic 🌈 that's the whole vibe. you call her, she handles the carrier-detect situation for you.

and why does she exist? for the moment, this is used to hide some internal details 🙈 — like, the messy stuff is tucked behind this nice little function so you don't have to look at it. very "don't worry about it bestie, I got you" of her.

heads up though 👀 — the docs literally say this will eventually become entirely internal to the tty port. so like, she's on her way to becoming a private girly. don't get too attached to calling her from the outside, iykyk 💀

🔥 SEE ALSO 🔥

no because the SEE ALSO section on this one ATE. it's giving family reunion. the whole tty_port extended universe is here 👑 and hey, the Kernel file is ./drivers/tty/tty_port.c — that's where she lives, go say hi 🏠

like I said. the whole squad. go read them too, they're all slaying in their own lanes 🌟

and that's the page, babe 🫶 sourced from ./drivers/tty, dated October 2026, served up fresh from the Kernel API Manual — mwah, go check that carrier, ily, bye 💋💖
