llc_ui_shutdown(9)

💖 NAME 💖

okay so bestie, welcome to llc_ui_shutdown(9) from the Kernel API Manual — the manual name is folded right in here so we’re not copying the header line, slay. This page’s whole NAME vibe is: llc_ui_shutdown — shutdown a connect llc2 socket. 💅

✨ SYNOPSIS ✨

int llc_ui_shutdown (struct socket *sock , int how );

that’s the signature, literally exactly like that. no edits, no cap. 🫶

🎀 ARGUMENTS 🎀

• sock — the socket to shutdown. like, the one getting the goodbye vibes. 🦋
• how — what part of the socket to shutdown. this is the “which shutdown flavor” parameter, bestie. 💫

🦋 DESCRIPTION 🦋

So this function shuts down a connected llc2 socket. Currently it only supports shutting down both sends and receives (2) — the docs are like, yeah, we could probably make this function such that a user can shutdown only half the connection, but not right now. 😭

bestie, the current vibe is: both sends and receives (2), or nothing. the half-shutdown situation is not happening rn. 💀

🌸 RETURN 🌸

Returns 0 upon success, negative otherwise. ✨ so 0 is the slay, negative is the not-so-slay. 😌
