📦 version 7.3.1, in nixpkgs unstable

✨ tipc_msg_reverse ✨

okay so bestie, welcome to the tipc_msg_reverse(9) page — straight out of the Kernel API Manual 💅 this one's a tiny little function with a whole lot of attitude: it literally flips a message around and slaps an error code on it. icon behavior, honestly.

💖 NAME 💖

tipc_msg_reverse — swap source and destination addresses and add error code

like... it takes a message, turns it around so it's going back where it came from, and tacks on an error code. reversal slay 🔥

🦋 SYNOPSIS 🦋

bool tipc_msg_reverse (u32 own_node , struct sk_buff **skb , int err );

she's a bool, she takes three args, she's doing the most. periodt. 👑

🎀 ARGUMENTS 🎀

  • own_node — the originating node id for the reversed message 🌸 like, who's this message actually from now that we've flipped it?
  • skb — buffer containing the message to be reversed; will be consumed 💀 heads up bestie, this buffer gets eaten. gone. it replaces the consumed buffer with a new one when successful, so don't go holding onto the old one, iykyk.
  • err — error code to be set in the message, if any 🙈 (yes, "if any" — sometimes there's just no error to report and that's valid)
ngl the skb situation is the main character here — it gets consumed, and on success you get a brand new buffer in its place. don't get attached to the original, fr fr.

⭐ RETURN ⭐

true if success, otherwise false 🫶 that's it, that's the whole vibe check.
