fdt_string(9)

✨ NAME ✨

okay so bestie, welcome to fdt_string(9) — the manual page for fdt_string. It's literally the function that retrieves a pointer to a single string from the strings block of a device tree. tiny function, very demure 💅.

📜 SYNOPSIS 📜

const char * fdt_string (const void *fdt , int stroffset );

🧾 ARGUMENTS 🧾

• fdt — pointer to the device tree blob. that's the blob, bestie.
• stroffset — offset of the string within the strings block (native endian). native endian, no cap.

💖 DESCRIPTION 💖

So fdt_string retrieves a pointer to a single string from the strings block of the device tree blob at fdt. That's the whole vibe: you point it at the blob and the offset, and it gives you a pointer to one string in the strings block. slay ✨.

🔁 RETURN 🔁

On success, you get a pointer to the string. If stroffset is out of bounds, or doesn't point to a valid string, you get NULL. that's the return contract, periodt 💜.
