💖 fdt_finish(9) — Kernel API Manual 💖

okay so bestie, welcome to the glow-up page for fdt_finish(9) — yes that's the manual section in the parentheses, we're being official today ✨

🌸 NAME 🌸

fdt_finish — the moment where your device tree creation arc finally gets its main character finale 🎀

✨ SYNOPSIS ✨

int fdt_finish (void *fdt );

like, that's it. one function. one pointer. one little completion ceremony 💅

🦋 ARGUMENTS 🦋

  • fdt — a pointer to the device tree blob 🫶 literally just hand it the blob and let it cook.

👑 DESCRIPTION 👑

so fdt_finish is the finishing bestie. it completes the whole device tree creation process that you started earlier with fdt_create. think of it like the last brush of lip gloss before you walk out the door 💄

this function finalizes the device tree blob and makes it ready for use. after you call it, the blob is complete, and you can use it with the libfdt read-only and read-write functions — but not with the sequential write functions. ngl that part matters, so don't come for me if you try it 🙈

⭐ RETURN ⭐

  • 0 — on success, slay 💅✨
  • -FDT_ERR_BADSTATE — when the sequential write process is incomplete 😭 like bestie the story isn't finished yet, you can't end the chapter early

🌈 SEE ALSO 🌈

and that's the whole page bestie, you ate that 🍓💜

shoutout to ./scripts/dtc/libfdt for birthing this iconic file, dated October 2026 — mwah, xoxo 💋
