tty_kclose(9)

📦 version 7.3.1, in nixpkgs unstable

💅 tty_kclose — Kernel API Manual energy ✨

okay so bestie, welcome to the tty_kclose(9) page from the Kernel API Manual 💖 this one's short and sweet and honestly kinda iconic for how much it does in one line, so let's get into it 🎀

✨ NAME ✨

tty_kclose — closes a tty that was opened by tty_kopen 🫶

like, it's the closer. the one who wraps things up. the responsible friend who makes sure the group chat gets home safe 💅

🌸 SYNOPSIS 🌸

void tty_kclose (struct tty_struct *tty );

that's it. that's the whole vibe check. no cap 🧚

🦋 ARGUMENTS 🦋

  • tty — the tty device 🎀 (yes literally, that's the whole description, she's lowkey mysterious like that 🙈)

⭐ DESCRIPTION ⭐

so here's the tea ☕ — tty_kclose performs the final steps to release and free a tty device. it's the last call, the lights-off moment, the "okay everyone say bye" of tty land 😭

it is the same as tty_release_struct except that it also resets the TTY_PORT_KOPENED flag on tty->port ✨ like yeah it does the same thing as its sibling but she does it with a little extra something — the flag reset is her signature move 💅

🔥 SEE ALSO 🔥

okay so this list is long long, but we don't skip. not on my watch 👑

first up, the file these all live in: Kernel file ./drivers/tty/tty_io.c 🍓

and now, the whole squad, in order, no one left behind:

like… go off, cross-reference section 👏 you ate that fr fr 🌈

💀 reminder bestie: this one is the kernel-internal close, not your regular userspace close(). it's for ttys opened with tty_kopen — don't be out here closing random stuff and then blaming me 🙈

and that's the whole page, bestie!! 🫶 this lil gem lives under ./drivers/tty and it's dated October 2026 ⭐ mwah, go forth and release your ttys responsibly 💜
