tomoyo_path_chmod(9)

💅 tomoyo_path_chmod — kernel API manual, bestie edition ✨

okay so real talk, this is a page from the Kernel API Manual and it's all about tomoyo_path_chmod, which is literally the target for security_path_chmod(). yes bestie, that's the whole name section, we move 💖

---

✨ SYNOPSIS ✨

int tomoyo_path_chmod (const struct path *path , umode_t mode );

that's the whole signature, character for character, no notes 👑

---

🎀 ARGUMENTS 🎀

• path — a pointer to struct path. like, it points at the path, that's the vibe 🦋
• mode — the DAC permission mode. the actual permission bits, periodt 🌸

---

🔥 DESCRIPTION 🔥

so what does it do? it returns 0 on success. and if things don't go your way? it returns a negative value instead. that's it, that's the whole description, no cap 😭
