parse_version(9)

💖 parse_version(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel section, section 9, and today's main character is parse_version. she parses a policy version. that's it, that's the vibe. ✨

---

🌸 NAME 🌸

parse_version — parse the policy version, fr fr. that's her whole job and she ate. 💅

---

🦋 SYNOPSIS 🦋

int parse_version (char *ver , struct ipe_parsed_policy *p );

like yes she returns an int and takes two things, we'll get to those 🫶

---

🎀 ARGUMENTS 🎀

• ver — supplies a version string to be parsed. it's the string, the raw material, the little text she's gonna chew on. give her a string and she'll tell you if it's a version or a disaster. 🍓
• p — supplies the partial parsed policy. it's the partial parsed policy, not the whole thing, so don't come at her with a finished one, she's mid-parse, she's in her process. 💜

---

⭐ RETURN ⭐

the return values, so you know what you got back — no guessing, no cap:

• 0 — Success 🌈
• -EBADMSG — Version string is invalid 😭 (the string said something unhinged, she's rejecting it)
• -ERANGE — Version number overflow 💀 (numbers got too big, they're doing way too much)
• -EINVAL — Parsing error 🙈 (just a parsing error, it happens, we move)

bestie, note the vibes: 0 is the slay, everything else is a negative errno and you should go check yourself before you wreck yourself. 🔥
