smk_parse_rule(9)

💅 smk_parse_rule(9) — like, the Kernel API Manual edition, bestie 🎀

okay so real talk, this whole page lives in the Kernel API Manual, and the star of the show is smk_parse_rule — a function whose entire personality is "turn a load string into a Smack rule." no cap, that's the vibe. ✨

---

🌸 NAME 🌸

smk_parse_rule — parse a Smack rule from a load string. literally that's it, that's the job 🫶

---

✨ SYNOPSIS ✨

int smk_parse_rule (const char *data , struct smack_parsed_rule *rule ,
       int import );

---

🎀 ARGUMENTS 🎀

• data — the string to be parsed, and bestie its size is SMK_LOADLEN. that's a fixed-size situation, so don't come at it with whatever length you want 💀
• rule — the Smack rule. that's the thing you're filling in, main character energy fr fr 👑
• import — if it's non-zero, the labels get imported. if it's zero, they don't. simple as 🌈

---

🦋 DESCRIPTION 🦋

returns 0 on success, and -1 on errors. that's the whole mood board, honestly — zero means slay, minus one means something went sideways 😭

lowkey important: -1 is the error signal here, so always vibe check that return value before you keep going.
