xas_error(9)

💖 xas_error — Kernel API Manual, section 9 💖

Bestie, welcome to the xas_error page from the Kernel API Manual, section 9. It’s giving tiny-but-important xarray energy. 🦋

---

🌸 NAME 🌸

xas_error — Return an errno stored in the xa_state.

---

✨ SYNOPSIS ✨

int xas_error (const struct xa_state *xas );

---

🎀 ARGUMENTS 🎀

• xas — XArray operation state. That’s the state bestie; it’s the thing you’re checking. 💅

---

💜 RETURN 💜

• 0 if no error has been noted.
• A negative errno if one has.

Like, literally that’s the vibe check: 0 means no error was noted, and a negative errno means one was. No cap. 🌈
