okay so this is a page from the Kernel API Manual and it's literally about qcomtee_supp_send, bestie, keep up 🫶

✨ NAME ✨

qcomtee_supp_send — Submit a response for a request. that's it. that's the whole gig 💅

---

🦋 SYNOPSIS 🦋

int qcomtee_supp_send (struct tee_context *ctx , u32 errno , u32
num_params , struct tee_param *params );

no cap, that's the exact signature, don't come for me about the line break, it's canon 😭

---

🎀 ARGUMENTS 🎀

• ctx — TEE context. the whole vibe check of where we're operating, y'know?
• errno — return value for the request. yeah it's literally called errno, we love a self-explanatory lil guy ✨
• num_params — number of elements in the parameter array. gotta know how many we're working with, fr fr.
• params — returned parameters. the actual goods being sent back 💖

---

🌸 DESCRIPTION 🌸

okay so the main character here is the first parameter. it's a meta TEE_IOCTL_PARAM_ATTR_TYPE_VALUE_OUTPUT — say that five times fast, i dare you 💀

the way that first param works: it specifies the request ID this response belongs to. so like, every response knows exactly which request it's replying to. iconic matching behavior, honestly 👑

---

⭐ RETURN ⭐

• On success, returns 0 🎉
• on failure, returns < 0 😭

that's it. that's the whole return section. short and slay.
