au_write_buf(9)

🦋 au_write_buf(9) — the Kernel API Manual glow-up 🦋

okay so bestie, we're in the Kernel API Manual today and the star of the show is au_write_buf(9). yes it's a manual page about a function, no it's not boring, stay with me 💅

✨ NAME ✨

au_write_buf — write buffer to chip 🫶

like. that's literally her whole job. she writes a buffer. to a chip. iconic behavior honestly 👑

---

🌸 SYNOPSIS 🌸

void au_write_buf (struct nand_chip *this , const void *buf , unsigned
int len );

that's the whole signature, no cap — it returns void, so no return value to check, she just does the thing and dips 😭

---

🎀 ARGUMENTS 🎀

• this — the NAND chip object. this is the chip we're talking to, the main character of the operation 🧚
• buf — data buffer. this is where the bytes are coming from ✨
• len — number of bytes to write. yes bestie, we're counting them, precision matters 💖

---

💜 DESCRIPTION 💜

it's the write function for 8bit buswidth — that's the vibe, that's the whole description, and she ate 🌈

so when you need to push a buffer out to the chip on an 8-bit-wide bus, this is the one you call. simple, clean, does exactly one thing, we love a focused queen 🎀
