📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay bestie, this is the mtd_ooblayout_set_bytes(9) page from the Kernel API Manual ✨ — and it's literally about one thing: putting OOB bytes into the oob buffer 🎀.

mtd_ooblayout_set_bytes — put OOB bytes into the oob buffer 💾

✨ SYNOPSIS ✨

int mtd_ooblayout_set_bytes (struct mtd_info *mtd , const u8 *buf , u8
       *oobbuf , int start , int nbytes , int (*iter)(struct mtd_info *, int
       section, struct mtd_oob_region *oobregion) );

🎀 ARGUMENTS 🎀

  • mtd — the mtd info structure, aka the main character of this call 👑
  • buf — source buffer to get OOB bytes from, the stash of data 💖
  • oobbuf — the OOB buffer, where the bytes are headed 🎀
  • start — first OOB byte to set, the starting point bestie ✨
  • nbytes — number of OOB bytes to set, the count fr fr 🔢
  • iter — section iterator, no cap 🌀

💖 DESCRIPTION 💖

okay so mtd_ooblayout_set_bytes fills the OOB buffer with the data provided in buf 💾. The category — ECC or free — is selected by passing the appropriate iterator. That's the whole move ✨.

It returns zero on success, and a negative error code otherwise 🫶. That's it, that's the tea ☕.
