💖 cipso_v4_map_lvl_hton — Kernel API Manual ✨

okay so bestie, we're in the <purple>Kernel API Manual</purple> today and this little cutie is cipso_v4_map_lvl_hton(9). she's lowkey the translator of the MLS world, and honestly? she ate. let's get into it 🫶

🌸 NAME 🌸

cipso_v4_map_lvl_hton — literally the glow-up that performs a level mapping from the host to the network 💅

✨ SYNOPSIS ✨

int cipso_v4_map_lvl_hton (const struct cipso_v4_doi *doi_def , u32
host_lvl , u32 *net_lvl );

no cap, that's the whole signature. we do NOT edit it. we respect her 🎀

🦋 ARGUMENTS 🦋

  • doi_def — the DOI definition 👑 this is the blueprint she's working from
  • host_lvl — the host MLS level 🌸 the local vibes, so to speak
  • net_lvl — the network/CIPSO MLS level 🦋 the vibes after the group chat translation

💜 DESCRIPTION 💜

so what does she actually do? she performs a label mapping to translate a local MLS level into the correct CIPSO level, using the given DOI definition. think of it as her taking your host-side level and matching it to the network-side level so everybody's speaking the same language 💬✨

and the return? zero on success 🎉 negative values otherwise 😭 that's it, that's the whole mood.

heads up bestie: zero = slay, negative = something went sideways. no in-between. periodt.
