fdt_strerror(9)

✨ NAME ✨

fdt_strerror(9) is the Kernel API Manual bestie that gives you a string description of an error code. Like, you hand it the error code, it hands back the words. No cap. 💅

---

🫶 SYNOPSIS 🫶

Vibe check: here’s the exact signature, bestie — do not lose the spacing:

const char * fdt_strerror (int errval );

---

🎀 ARGUMENTS 🎀

• errval — the error code that a libfdt function returned. That’s the one you pass in, periodt.

---

🌸 DESCRIPTION 🌸

fdt_strerror returns a string description of the error code passed in errval. That’s the whole assignment, and it ate. 💖

---

👑 RETURN 👑

A pointer to a string describing the error code. Yup, that’s the return value — iconic. ✨
