OPTEE_MSG_GET_ARG_SIZE(9)

💖 OPTEE_MSG_GET_ARG_SIZE(9) 💖

okay so this is a page from the Kernel API Manual, bestie — it's OPTEE_MSG_GET_ARG_SIZE(9) and it's genuinely so short you could read it in the time it takes to microwave a bagel. but we're gonna give it the respect it deserves anyway 🫶

---

✨ NAME ✨

OPTEE_MSG_GET_ARG_SIZE — literally just returns the size of struct optee_msg_arg. that's it. that's the whole job. icon behavior honestly 👑

---

🌸 SYNOPSIS 🌸

OPTEE_MSG_GET_ARG_SIZE (num_params );

yes the space before the paren is real, don't come for me, that's just how it's written 💅

---

🎀 ARGUMENTS 🎀

• num_params — the number of parameters embedded in the struct optee_msg_arg. like, how many lil param besties are living inside it 🦋

---

🦋 DESCRIPTION 🦋

okay so what this does: it returns the size of the struct optee_msg_arg together with the number of embedded parameters. so you're not just getting the struct's size, you're getting the struct plus all the params stuffed in there. the whole package. the full fit ✨

no cap, that's the entire description. short and slay 💀

ngl this page is a little snack-sized one, but every single word of it matters, so don't skip the struct references up there — they're the main character energy of the whole thing 🌈

and that's a WRAP, bestie 🎀 this lil page lives over at ./drivers/tee/optee, dated October 2026, and it goes by OPTEE_MSG_GET_ARG_SIZE(9) — memorize it, screenshot it, put it on your lockscreen, whatever you gotta do 💜✨🔥
