💖 optee_supp_recv(9) — Kernel API Manual 💖

okay so bestie, welcome to the optee_supp_recv page — this is the 9 section of the Kernel API Manual, and we're literally about to make supplicant request-receiving make sense. periodt. ✨

🌸 NAME 🌸

optee_supp_recv — receive request for supplicant 🫶

🦋 SYNOPSIS 🦋

int optee_supp_recv (struct tee_context *ctx , u32 *func , u32
       *num_params , struct tee_param *param );

that's the whole vibe. one function, four args, no cap. 💅

🎀 ARGUMENTS 🎀

  • ctx — the context that's receiving the request. like, whose inbox is this landing in. 📥
  • func — the requested function in the supplicant. the "what do they want from me" energy. ✨
  • num_params — the number of elements allocated in param, and it gets updated with the number of used elements. yes bestie, it's an in-and-out situation — it comes in as the count and leaves telling you how many actually got used. 🔄
  • param — the space for parameters for func. this is where the actual deets live. 🧚

⭐ DESCRIPTION ⭐

returns 0 on success or <0 on failure. that's it, that's the whole story — check the return value, always, i'm begging. 😭

and that's a wrap, bestie 🎀 this little beauty lives in ./drivers/tee/optee and it's dated October 2026 — mwah, slay, bye 💅💖
