💅 panthor_vm_is_unusable(9) — Kernel API Manual ✨

Okay so bestie, welcome to panthor_vm_is_unusable — yes it's from the Kernel API Manual, no it's not scary, I promise. It's literally the vibe-check function for a VM. Sit down, hydrate, let's go 🫶

---

🌸 NAME 🌸

panthor_vm_is_unusable — the little guy that checks whether a VM is still usable or whether it's, like, going through it 😭

---

🦋 SYNOPSIS 🦋

bool panthor_vm_is_unusable (struct panthor_vm *vm );

That's it. That's the whole call. Bool in, bool out, slay ✨

---

🎀 ARGUMENTS 🎀

• vm — the VM you want to check, bestie. Hand it over and it'll get inspected. 👀

---

👑 RETURN 👑

Lowkey simple: it hands back true if the VM is unusable, and false otherwise. That's the whole truth, no cap 💯
