🦋 mtd_ooblayout_get_eccbytes 🦋

okay so welcome to the Kernel API Manual, bestie — this page is all about mtd_ooblayout_get_eccbytes, and it's literally the move for pulling ECC bytes out of the OOB buffer. 💖

🌸 NAME 🌸

mtd_ooblayout_get_eccbytes — extract ECC bytes from the oob buffer.

✨ SYNOPSIS ✨

int mtd_ooblayout_get_eccbytes (struct mtd_info *mtd , u8 *eccbuf ,
       const u8 *oobbuf , int start , int nbytes );

🫶 ARGUMENTS 🫶

• mtd — the mtd info structure. 🧚
• eccbuf — destination buffer to store ECC bytes. 💅
• oobbuf — the OOB buffer.
• start — first ECC byte to retrieve.
• nbytes — number of ECC bytes to retrieve.

💖 DESCRIPTION 💖

It works like mtd_ooblayout_get_bytes, except it acts on ECC bytes. That's the whole flex. ✨

Returns zero on success, a negative error code otherwise. No cap. 👑
