kernel_to_ipc64_perm(9)

💅 kernel_to_ipc64_perm(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're in the kernel docs now, and yes it's giving main character energy ✨ this one's a little function that flips kernel-side ipc perms into the user-facing glow-up version. let's get into it 🫶

---

✨ NAME ✨

kernel_to_ipc64_perm — convert kernel ipc permissions to user

---

🎀 SYNOPSIS 🎀

void kernel_to_ipc64_perm (struct kern_ipc_perm *in , struct ipc64_perm
*out );

---

🌸 ARGUMENTS 🌸

• in — kernel permissions 👑 the in-kernel version, the original, the blueprint
• out — new style ipc permissions 💖 the fresh-out-the-salon, userspace-ready version

---

🦋 DESCRIPTION 🦋

okay so literally what happens is: you take the kernel object in and you turn it into a set of permissions descriptions for returning to userspace (out). that's it, that's the whole vibe. it's a glow-up pipeline, no cap ✨
