teedev_open(9)

💖 teedev_open(9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the teedev_open page from the Kernel API Manual — it's a whole section 9 manpage and honestly it's short but she's iconic 🎀

---

✨ NAME ✨

teedev_open — literally just opens a struct tee_device 🫶

---

🌸 SYNOPSIS 🌸

struct tee_context * teedev_open (struct tee_device *teedev );

that's it. that's the whole function signature. the way she takes one struct tee_device * and hands you back a struct tee_context * — main character energy fr fr ✨

---

🦋 ARGUMENTS 🦋

• teedev — the device you wanna open, bestie. that's the one. 💅

---

⭐ RETURN ⭐

• you get a pointer to struct tee_context on success — slay 👑
• or an ERR_PTR on failure — and yes that's a real thing, no cap, so please check it with the usual error-checking macros before you go dereferencing anything 😭

ngl if you skip the error check you're gonna have a bad time. the kernel does not do vibes-based error handling 💀
