qcomtee_params_from_args(9)

💖 qcomtee_params_from_args — the glow-up from QTEE args to TEE params 💖

okay so welcome to section 9 of the Kernel API Manual, bestie 🎀 this is the page for qcomtee_params_from_args(9), and honestly it's giving "closing time at the QTEE club" energy. let's get into it ✨

---

✨ SYNOPSIS ✨

int qcomtee_params_from_args (struct tee_param *params , struct
qcomtee_arg *u , int num_params , struct tee_context *ctx );

that's the whole signature, no cap — copy it exactly or the compiler will simply end you 💀

---

🌸 ARGUMENTS 🌸

• params — the TEE parameters. this is where stuff gets put, bestie 💅
• u — the QTEE arguments. the source material 🫶
• num_params — the number of elements in the parameter array. literally how many you're working with, fr fr.
• ctx — the context in which the conversion should happen. the vibe check location, if you will 👑

---

🦋 DESCRIPTION 🦋

so like. u should have already been initialized by qcomtee_params_to_args. important!! that's the prerequisite, no shortcuts 🎀

and here's the iconic part: this call also represents the end of a QTEE invocation that started with qcomtee_params_to_args, because it releases the QCOMTEE_ARG_TYPE_IO objects. so like, it's the closing bracket of the whole thing 🧚 main character energy of a cleanup function, honestly. 💜

🌈 RETURN 🌈

• On success, returns 0 🎉 slay.
• On failure, returns < 0 😭 (i.e. a negative value — go check your stuff).

⭐ SEE ALSO ⭐

ok but seriously — if you're touching the params, read qcomtee_params_to_args(9) first, since this whole page assumes you already called it. matching set, iykyk 💅
