tty_driver_flush_buffer(9)

💅 NAME 💅

okay so bestie, welcome to the tty_driver_flush_buffer(9) page — we’re in the Kernel API Manual, and yes, the manual name is folded in right here instead of copying the header line. cute, right? 🎀

• tty_driver_flush_buffer — discard internal buffer

✨ SYNOPSIS ✨

void tty_driver_flush_buffer (struct tty_struct *tty );

🌸 ARGUMENTS 🌸

• tty — the terminal. that’s it, that’s the whole argument, and she’s the main character here 💖

🦋 DESCRIPTION 🦋

Bestie, this function says: discard the internal output buffer for this device. That’s the assignment. 🫶

If no method is provided, then either the buffer cannot be hardware flushed or there is no buffer driver side. No cap — that’s exactly the caveat the page drops, so don’t act surprised. 😭
