tty_kref_get(9)

tty_kref_get 💅✨

okay so this page is from the Kernel API Manual, and it's literally about tty_kref_get — the function that gets a tty reference. no cap, bestie, it's giving tiny-but-important kernel helper energy. 🎀

✨ NAME ✨

tty_kref_get — get a tty reference, periodt. 💖

🌸 SYNOPSIS 🌸

the signature is exactly this, don't come for me:

struct tty_struct * tty_kref_get (struct tty_struct *tty );

🎀 ARGUMENTS 🎀

• tty — the tty device in question. that's the whole argument, bestie. 💅

🦋 RETURN 🦋

you get back a new reference to a tty object ✨. slay.

💜 DESCRIPTION 💜

Locking: the caller has to be holding sufficient locks/counts to ensure that their existing reference cannot go away. read that again, bestie — if you don't have enough locks/counts holding your current reference down, it might go poof, and that's not the vibe. 💀

🌈 SEE ALSO 🌈

• Kernel file ./include/linux/tty.h — main character behavior, honestly. check out struct tty_struct(9), enum tty_struct_flags(9), and tty_get_baud_rate(9) too, fr fr. 🦋

okay bye bestie — this came from ./include/linux, dated October 2026, and it's all about tty_kref_get(9) 🫶💖
