tty_port_tty_set(9)

💅 tty_port_tty_set(9) — the Kernel API Manual bestie era

okay so welcome to the Kernel API Manual page for tty_port_tty_set(9), we're literally in ./drivers/tty land and it's giving very much "tiny function, big responsibilities" ✨

---

🌸 NAME 🌸

tty_port_tty_set — set the tty of a port, no cap 🎀

---

🦋 SYNOPSIS 🦋

void tty_port_tty_set (struct tty_port *port , struct tty_struct *tty );

like that's it, that's the whole signature, she's simple and she's iconic 💅

---

🍓 ARGUMENTS 🍓

• port — the tty port. your port. the one you're matching up 🫶
• tty — the tty. the other half of this little situationship 💖

---

👑 DESCRIPTION 👑

okay so here's the tea: this function associates the port and tty pair, like officially, like they're linked now 🎀 and yes she manages any internal refcounts for you because she's a responsible queen, no notes ✨

and the big one — if you pass NULL as the tty, that deassociates the port. it's the breakup arc 💀 lowkey sad but highkey necessary.

fr fr: NULL here isn't an error, it's the actual documented way to deassociate a port. don't panic when you see it 🙈
