tty_buffer_free_all(9)

🌸 NAME: tty_buffer_free_all(9) 🌸

okay bestie, this one is from the Kernel API Manual, and the whole vibe is literally “free buffers used by a tty.” 💅

✨ SYNOPSIS ✨

void tty_buffer_free_all (struct tty_port *port );

🎀 ARGUMENTS 🎀

• port — the tty port you’re freeing from. that’s the one, no cap 🫶

🦋 DESCRIPTION 🦋

This function removes all the buffers pending on a tty — whether they’re queued with data or just chilling in the free ring. 🧹✨

It must be called when the tty is no longer in use. like, do not come for this function while the tty is still main-character-ing, okay? 😭
