get_require..._open_access(9)

💅 get_require..._open_access(9) 💅

okay so bestie, welcome to section 9 of the Kernel API Manual 🦋 — yes, the grown-up kernel-section one — and today's main character is get_required_file_open_access, a name so long the header literally had to abbreviate it to get_require..._open_access(9) 😭 iconic behaviour honestly.

🌸 SYNOPSIS 🌸

access_mask_t get_required_file_open_access (const struct file *const
file );

🎀 ARGUMENTS 🎀

• file — the file being opened. that's it, that's the whole argument, she's lowkey simple like that 🙈

---

⭐ RETURN ⭐
