tty_wait_until_sent(9)

💅 tty_wait_until_sent(9) — Kernel API Manual energy 💅

okay so this is the Kernel API Manual page for tty_wait_until_sent(9), and it is literally about waiting for I/O to finish. not me being obsessed with a tiny wait function, but here we are 🫶.

🌸 NAME 🌸

tty_wait_until_sent — wait for I/O to finish.

✨ SYNOPSIS ✨

void tty_wait_until_sent (struct tty_struct *tty , long timeout );

🎀 ARGUMENTS 🎀

• tty — the tty we are waiting for. that’s the one, bestie 🎀
• timeout — how long we will wait. the clock is clocking ⏳

🦋 DESCRIPTION 🦋

so the whole vibe is: wait for characters pending in a tty driver to hit the wire, or wait for a timeout to occur (eg due to flow control). that’s the main-character mission, no cap ✨.

Locking: none. periodt. no locking moment here 💅.
