💖 add_rtas_mem_range(9) — a Kernel API Manual moment ✨

okay bestie, so this is a page from the Kernel API Manual (add_rtas_mem_range(9), we been knew) and honestly it's short but it ATE. let's get into it 🫶

---

🌸 NAME 🌸

add_rtas_mem_range — literally just adds the RTAS region to the memory ranges list you hand it. that's the whole vibe. no cap. 👑

---

✨ SYNOPSIS ✨

int add_rtas_mem_range (struct crash_mem **mem_ranges );

like yes, that's it, that's the whole signature 💅 note the double pointer babe, struct crash_mem **, we are modifying the thing.

---

🎀 ARGUMENTS 🎀

• mem_ranges — the range list you want the memory range added to. it's the list, and it's a struct crash_mem **, so bestie's getting touched (affectionately) 🦋

---

🌈 DESCRIPTION 🌈

okay so the function returns 0 on success ✨ and a negative errno on error 😭 that's literally the entire description, i know, i know, brief king behaviour 👑 but those are the facts and we respect them.

note: 0 = slay, negative errno = not slay. keep that in mind.
