doc_read_seek(9)

📦 version 7.3.1, in nixpkgs unstable

💅 doc_read_seek(9) — like, the Kernel API Manual's cutest little seek function 🎀

okay so bestie, welcome to the Kernel API Manual page for doc_read_seek(9) ✨ this one's short and sweet and honestly kind of a vibe — it just points the flash at the right spot so you can read from it. let's get into it 🫶

✨ NAME ✨

doc_read_seek — sets both flash planes to the specified block and page, for reading 📖💫

🌸 SYNOPSIS 🌸

int doc_read_seek (struct docg3 *docg3 , int block0 , int block1 , int
page , int wear , int ofs );

🦋 ARGUMENTS 🦋

  • docg3 — the device itself, the main character of this whole operation 👑
  • block0 — the block index of the first plane 🧚
  • block1 — the block index of the second plane 🧚
  • page — which page you want, within the block 📄
  • wear — if this is true, the read will happen on the 4 extra bytes of the wear area 🎀
  • ofs — the offset in the page where the read starts 📍

🔥 DESCRIPTION 🔥

So what it actually does: it programs the flash even and odd planes to that specific block and page you handed it. Both planes. At once. Iconic behaviour, no cap 💅

Or, if you're feeling different today — it programs the flash to the wear area of the page you specified instead 🌸

That's it. That's the whole thing. It's giving "set the coordinates, then go" ⭐
