🦋 SYNOPSIS 🦋

void vbg_core_exit (struct vbg_dev *gdev );

no cap, that's the whole signature. she's a void, she takes one pointer, she does her thing 💅

---

🎀 ARGUMENTS 🎀

• gdev — the Guest extension device. yeah. that one. hand her the struct vbg_dev * and she'll know what to do 🌸

---

👑 DESCRIPTION 👑

okay so here's the tea, and it's important tea: the native code should call this before the driver is loaded 🫡

⚠️ but do NOT call this on shutdown. fr fr. just don't. that's the whole warning, and it's giving "read it twice" energy 💀
