optee_supp_send(9)

💅 optee_supp_send — the Kernel API Manual moment bestie, section 9, let's GO 🎀

Okay so picture this: you're deep in the kernel, section 9 of the manual, living your main character life. That's where optee_supp_send(9) hangs out — this is literally the function that sends the result of a request from the supplicant back where it belongs. ✨

---

🌸 SYNOPSIS 🌸

int optee_supp_send (struct tee_context *ctx , u32 ret , u32 num_params
, struct tee_param *param );

Yes bestie, that's the whole signature, copied exactly, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• ctx — the context sending the result. It's giving "who's doing the sending" energy. 💅
• ret — the return value of the request. The receipts, if you will. 🧾
• num_params — how many parameters came back. Count 'em, queen. 🔢
• param — the actual returned parameters. The whole point, honestly. 👑

---

💖 DESCRIPTION 💖

So what does it do? Literally this: it returns 0 on success, or <0 on failure. That's it, that's the vibe check. 😭

Like, no complicated lore here — zero means we slayed, anything below zero means something went sideways. Periodt. 💀

🎀 SEE ALSO 🎀

• The kernel file ./drivers/tee/optee/supp.c — go read it, it's iconic 📖
• optee_supp_thrd_req(9) — the sibling you need to know about 🫶
• optee_supp_recv(9) — the other half of the friendship duo 💜
