calipso_getattr(9)

🌸 calipso_getattr — it's a Kernel API Manual moment, bestie 🌸

Okay so this is a page from the Kernel API Manual, section 9 — yes we're in kernel-land, hold my iced coffee 🧊☕ — and it's literally all about <hotpink>calipso_getattr</hotpink>. Say hi to her, she's the main character today 👑

---

✨ NAME ✨

calipso_getattr — grab the security attributes out of a memory block, no biggie 💅

---

🦋 SYNOPSIS 🦋

int calipso_getattr (const unsigned char *calipso , struct
netlbl_lsm_secattr *secattr );

That's the whole vibe check right there: it returns an int, takes a const unsigned char * named calipso, and a struct netlbl_lsm_secattr * named secattr. Slay 🫶

---

🎀 ARGUMENTS 🎀

• calipso — the CALIPSO option, fr. That's the thing you're inspecting, she's a const unsigned char * so hands off the contents, we're just looking 👀
• secattr — the security attributes, a struct netlbl_lsm_secattr *. This is where the good stuff lands ✨

---

💜 DESCRIPTION 💜

So what it actually does: it inspects calipso and returns the security attributes in secattr. Simple, iconic, no notes.

The returns are giving very binary-bestie energy: zero on success and negative values on failure 😭 so like, check your return value, bestie, don't just vibe and assume.

Ngl bestie, this one's short but she's important — recognize the return values or the failure will find you 💀
