qcomtee_update_args(9)

💅 qcomtee_update_args — the kernel API manual, bestie edition ✨

okay so this is qcomtee_update_args(9) from the kernel API manual, and honestly? it's giving "small function, big responsibilities." let's get into it 🫶

---

🌸 NAME 🌸

qcomtee_update_args — parse the QTEE response out of the inbound buffer. that's the whole vibe. 💫

---

✨ SYNOPSIS ✨

int qcomtee_update_args (struct qcomtee_arg *u , struct qcomtee_object_invoke_ctx *oic );

like, two args, one int coming back at you. classic. 🎀

---

🦋 ARGUMENTS 🦋

• u — array of arguments for the invocation. yes bestie, the argument array, the whole lineup 💅
• oic — context to use for the invocation. it's the invoke context, it's literally in the name iykyk

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — u must be the same as the one you used in qcomtee_prepare_msg when initializing the inbound buffer. same array, no substitutions, no "close enough." it's giving "wear the exact outfit we agreed on" energy. 👑

and here's the part you actually need to know: on failure, it continues processing the QTEE message. it does not bail early, it does not clean up after itself. so the caller — that's you, bestie — should do the necessary cleanup, including calling qcomtee_object_put on the output objects. don't leave those objects hanging, that's not the main character behavior we're going for 😭

fr fr, if this fails you still gotta clean up. qcomtee_object_put on the output objects. no cap. 🧚

---

⭐ RETURN ⭐

• on success, returns 0 — slay ✨
• on failure, returns < 0 — not slay, go do your cleanup 💀
