📦 version 7.3.1, in nixpkgs unstable

💅 llc_ui_connect — bestie, let's make a connection

okay so this is a page from the Kernel API Manual, and honestly? it's giving "networking but make it llc2." stay with me, we're gonna get through it together 🫶

✨ NAME ✨

llc_ui_connect — connect to a remote llc2 mac + sap. that's the whole vibe. that's what we do here. 💖

🦋 SYNOPSIS 🦋

int llc_ui_connect (struct socket *sock , struct sockaddr_unsized *uaddr
, int addrlen , int flags );

look at her. four whole arguments. she's iconic, she's lowercase, she's a kernel function. no cap.

🎀 ARGUMENTS 🎀

  • sock — the socket that's gonna get connected to the remote destination. she's the main character of this whole operation, fr.
  • uaddr — the remote address of the new connection… and possibly the local address too 👀. it's giving "who am i and where am i going" and tbh same.
  • addrlen — the size of the uaddr structure. like, how big is she. give the kernel the measurements please 🍓
  • flags — operational flags specified by the user. your lil knobs and switches. you do you. ✨

🌸 DESCRIPTION 🌸

lowkey the whole point: you're connecting to a remote llc2 mac + sap. simple as that. 💅

the caller must specify the destination mac and address to connect to. no destination, no connection, no slay. periodt.

here's the tea though — if the user hasn't previously called bind(2) with a smac, then the address of the first interface of the specified arp type will be used instead. the kernel's just like "okay bestie, i got you, i'll pick one" 🫶

and bestie… this function will autobind if the user did not previously call bind. so like, don't stress if you forgot. she handles it. she's thoughtful like that. 😭💖

⭐ RETURN ⭐

  • 0 upon success 🎉
  • negative otherwise 💀

that's it. that's the whole return section. binary queen.

the lore, the extended universe, the friend group iykyk:

ngl, that llc_ui_autobind(9) entry is doing a lil foreshadowing for the DESCRIPTION section. love a callback. 🔥

okay that's the page!! this whole thing lives in ./net/llc, dated October 2026, and it's officially llc_ui_connect(9) — go connect to something remote, bestie, you've got this 💜🌈 slay responsibly ✨
