✨ NAME ✨

ipc_update_perm — update the permissions of an ipc object

Like, it goes in and changes the perms on an ipc thing. That's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int ipc_update_perm (struct ipc64_perm *in , struct kern_ipc_perm *out );

Returns an int, takes two pointers, we move. 😌

---

💖 ARGUMENTS 💖

• in — the permission given as input. This is the perms you're bringing to the table, the ones coming in. 🫶
• out — the permission of the ipc to set. This is the target, the perms getting updated, the one receiving the glow-up. ✨
