nand_read_page_op(9)

💅 nand_read_page_op(9)

okay so this is a page from the Kernel API Manual, section 9, and bestie, it's literally a whole vibe. it's about one (1) function and the function is nand_read_page_op. buckle up 🎀

---

✨ NAME ✨

nand_read_page_op — Do a READ PAGE operation 🫶

---

🌸 SYNOPSIS 🌸

int nand_read_page_op (struct nand_chip *chip , unsigned int page ,
       unsigned int offset_in_page , void *buf , unsigned int len );

like, that's the whole signature. gorgeous. iconic. no notes 💖

---

🦋 ARGUMENTS 🦋

• chip — The NAND chip. yes queen, this is the chip you're working with 👑
• page — page to read. the actual page, bestie 📄
• offset_in_page — offset within the page. so like, where inside page you're poking around 🙈
• buf — buffer used to store the data. the data goes in here, that's the whole point ✨
• len — length of the buffer. how much room you've got, ngl don't overrun it 💀

---

🌈 DESCRIPTION 🌈

This function issues a READ PAGE operation. that's it, that's the job. main character energy 🔥

but — and this is the important part, so listen — this function does not select/unselect the CS line. it's giving "i don't do my own line management" 💅 so handle that yourself, iykyk.

Returns 0 on success, a negative error code otherwise. so if you get a negative number back, that's a fail, no cap 😭

okay this list is a LOT, but we're doing the whole thing because every single one of these matters, periodt 🧚
