TEE_IOC_INVOKE(9)

💅 TEE_IOC_INVOKE(9) — like, the Kernel API Manual, bestie 🎀

okay so welcome to the <pink>TEE_IOC_INVOKE</pink> page, part of the <purple>Kernel API Manual</purple> ✨ pull up a chair, grab a strawberry 🍓, we're learning ioctls today and honestly? it's gonna slay.

🌸 NAME 🌸

TEE_IOC_INVOKE — invokes a function in a Trusted Application 💅 like you literally call into the Trusted App and it does the thing, no cap.

---

🦋 SYNOPSIS 🦋

TEE_IOC_INVOKE

that's it. that's the whole synopsis. iconic minimalist behaviour honestly 👑

---

✨ DESCRIPTION ✨

so here's the vibe: <mint>TEE_IOC_INVOKE</mint> takes a struct tee_ioctl_buf_data 😌 and that struct contains a struct tee_invoke_func_arg, which is then followed by any array of struct tee_param — yes bestie, an array, meaning zero or more of them, it's giving flexible ✨

so the layout is literally like:

struct tee_ioctl_buf_data

…wrapping a struct tee_invoke_func_arg…

…and then trailing behind it, any array of struct tee_param 🫶

that's the whole description, she's short but she ate 💀
