💖 calipso_init(9) 💖

okay so this is a page from the Kernel API Manual — it's calipso_init(9), and yes bestie, we're getting into the CALIPSO module today 🎀

✨ NAME ✨

calipso_init — literally the function that initializes the CALIPSO module 🦋

🌸 SYNOPSIS 🌸

int calipso_init (void );

⭐ ARGUMENTS ⭐

  • void — no arguments, bestie. absolutely none. it takes nothing and it's iconic for that 💅

👑 DESCRIPTION 👑

So what does it do? It initializes the CALIPSO module and gets it all prepped and ready for use ✨ like laying out the outfit the night before, except it's kernel networking.

It returns zero on success and negative values on failure — no cap, that's the whole contract 🙈

ngl, always vibe-check that return value. zero = slay, negative = something went wrong and you should care about it.

🔥 SEE ALSO 🔥

The kernel file lives at ./net/ipv6/calipso.c — that's the main character source file, iykyk 💜

and here's the whole friend group, every single one of them:

and that's the whole page, bestie 🫶 go initialize something beautiful. 💜
