xas_create_range(9)

💅 xas_create_range(9)

okay so this is a page from the Kernel API Manual bestie, and it's literally all about xas_create_range — yes that's a mouthful, we're coping 🫶

---

✨ NAME ✨

xas_create_range — bestie's whole job is making sure that stores to this range will actually succeed. no cap, that's the entire vibe check 🔥

---

🌸 SYNOPSIS 🌸

void xas_create_range (struct xa_state *xas );

that's it. that's the whole signature. she's simple, she's iconic 👑

---

🎀 ARGUMENTS 🎀

• xas — the XArray operation state. that's the little state baby you hand her and she does stuff to it. main character parameter fr fr

---

🦋 DESCRIPTION 🦋

so what actually happens: she creates all of the slots in the range that's covered by xas. every single one. not a vibe, not some of them — all of them ✨

then she sets xas to create single-index entries, and positions it at the beginning of the range. so after she's done, xas is sitting pretty at the start like "hi, i'm ready 💅"

and why, you ask? because this is for the benefit of users which have not yet been converted to use multi-index entries. yeah. it's a whole compatibility era situation — these users are still on single-index entries and this function is out here being the supportive bestie that makes their stores succeed anyway 😭🫶
