✨ nand_read_subpage(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's about nand_read_subpage, and it's literally the [REPLACEABLE] ECC-based sub-page read function. yes, replaceable in brackets, that's not a typo, that's the vibe. 🎀

🌸 NAME 🌸

nand_read_subpage — the [REPLACEABLE] ECC based sub-page read function, no cap 🫶

🦋 SYNOPSIS 🦋

int nand_read_subpage (struct nand_chip *chip , uint32_t data_offs ,
       uint32_t readlen , uint8_t *bufpoi , int page );

that's the whole signature, she's serving function prototype energy 👑

💅 ARGUMENTS 💅

  • chip — the nand chip info structure. like, the whole personality profile of the chip you're messing with 🧚
  • data_offs — offset of the requested data within the page. yes, within the page, don't go outside 🍓
  • readlen — data length. how much you're reading, obvs 💜
  • bufpoi — buffer to store read data. this is where the good stuff lands ✨
  • page — page number to read. which page, bestie, which page 🌈
seriously though, all five of these matter — skip one and it's giving undefined nonsense 😭
