mtd_ooblayout_find_region(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

mtd_ooblayout_find_region(9) — hiiii bestie, this one's from the Kernel API Manual — is literally Find the region attached to a specific byte. No cap, that's the whole vibe. 💅

✨ SYNOPSIS ✨

int mtd_ooblayout_find_region (struct mtd_info *mtd , int byte , int
*sectionp , struct mtd_oob_region *oobregion , int (*iter)(struct
mtd_info *, int section, struct mtd_oob_region *oobregion) );

🎀 ARGUMENTS 🎀

Okay so here's the cast of characters, bestie:

  • mtd — mtd info structure.
  • byte — the byte we are searching for.
  • sectionp — pointer where the section id will be stored.
  • oobregion — used to retrieve the ECC position.
  • iter — iterator function. Should be either mtd_ooblayout_free or mtd_ooblayout_ecc depending on the region type you're searching for.

🦋 DESCRIPTION 🦋

This function returns the section id and oobregion information of a specific byte. Like, imagine you're trying to figure out where the 4th ECC byte is stored — you'll use this exact call:

mtd_ooblayout_find_region(mtd, 3, section, oobregion,
mtd_ooblayout_ecc);

Returns zero on success, a negative error code otherwise. Periodt. 💖
