mtd_ooblayou...nd_eccregion(9)

✨ NAME ✨

okay so like, this is mtd_ooblayout_find_eccregion — the little function whose whole personality is finding the ECC region that's attached to one specific ECC byte 🎯 she's a Kernel API Manual girlie, very official, very demure 💅

🌸 SYNOPSIS 🌸

int mtd_ooblayout_find_eccregion (struct mtd_info *mtd , int eccbyte ,
       int *section , struct mtd_oob_region *oobregion );

🎀 ARGUMENTS 🎀

• mtd — the mtd info structure, like, the whole vibe context bestie 🌈
• eccbyte — the byte we are searching for 👀 literally the main character of this search
• section — a pointer where the section id is gonna get stored, so she can report back 🫶
• oobregion — OOB region information, all the deets about the region ✨

🦋 DESCRIPTION 🦋

okay so real talk — she works exactly like mtd_ooblayout_find_region, no cap, except instead of a normal search she's hunting down one specific ECC byte 🧚 same energy, different target.

Returns zero on success, and a negative error code otherwise 😭 (so like, check your return value, bestie, fr fr).
