ibmvmc_open(9)

✨ ibmvmc_open(9) ✨

okay so bestie, welcome to the ibmvmc_open page 💖 this one lives in the Kernel API Manual, and it's literally the "open a session" moment for the IBM VMC driver. tiny page, big main character energy 👑

---

🌸 NAME 🌸

ibmvmc_open — Open Session

like, it opens a session. that's the whole vibe. periodt 💅

---

🦋 SYNOPSIS 🦋

int ibmvmc_open (struct inode *inode , struct file *file );

ngl the signature is giving classic file-operation realness — int coming back at you, two pointers going in 🎀

---

💜 ARGUMENTS 💜

• inode — the inode struct 🗂️ that's what gets handed in here, no cap.
• file — the file struct 📄 and yep, that's the other one.

that's it. two structs. iconic minimalism ✨

---

🔥 RETURN 🔥

• 0 — Success 🥳 slay, the session opened.
• Non-zero — Failure 💀 not slay, something went sideways.
