rtas_function_token(9)

💖 rtas_function_token — RTAS function token lookup 💖

okay so bestie, welcome to rtas_function_token(9) from the Kernel API Manual ✨ this one's short and sweet and honestly kind of iconic for it — it's literally just "hey, gimme the token for this RTAS function handle," and the kernel either hands you the goods or tells you nope, not on this platform 🎀

---

✨ SYNOPSIS ✨

s32 rtas_function_token (const rtas_fn_handle_t handle );

that's the whole vibe check right there 💅

---

🫶 ARGUMENTS 🫶

• handle — the function handle you're asking about, like RTAS_FN_EVENT_SCAN. that's your little ticket, your little name-tag for the RTAS function you want the token for 🎟️

---

🌸 CONTEXT 🌸

any context. literally any. no cap, no restrictions, she's flexible like that 🦋

---

⭐ RETURN ⭐

the token value for the function if this platform actually implements it. and if the platform doesn't? you get RTAS_UNKNOWN_SERVICE back. that's the "sorry babe, not here" answer 😭🙈
