tty_buffer_free(9)

tty_buffer_free(9) 💅

okay so this is a Kernel API Manual page, and the main character is tty_buffer_free — no cap, we're about to make buffer cleanup make sense. 🫶

✨ NAME ✨

tty_buffer_free — free a tty buffer. That's the whole vibe: it frees a tty buffer. 🎀

🌸 SYNOPSIS 🌸

void tty_buffer_free (struct tty_port *port , struct tty_buffer *b );

🦋 ARGUMENTS 🦋

• port — tty port owning the buffer, literally its keeper.
• b — the buffer to free, aka the one getting the free treatment.

🔥 DESCRIPTION 🔥

So what it does: frees a tty buffer, or adds it to the free list according to our internal strategy. It's giving cleanup with options — either free the buffer or tuck it onto the free list, following the internal strategy. 💀✨
