🌸 rsi_sdio_read_register_multiple — kernel API manual, bestie edition 🌸

okay so this is a page from the Kernel API Manual, and it's all about rsi_sdio_read_register_multiple. Yes the title is lowkey cursed and abbreviated as rsi_sdio_re...ter_multiple(9) — that's just how the manpage renders it, she's long, she's iconic, we deal. 💅

✨ NAME ✨

rsi_sdio_read_register_multiple — This function read multiple bytes of information from the SD card. 💖

Like, literally its whole personality is "grab a bunch of bytes off the SD card." That's the vibe. 🦋

🎀 SYNOPSIS 🎀

int rsi_sdio_read_register_multiple (struct rsi_hw *adapter , u32 addr ,
u8 *data , u16 count );

She takes four args and returns an int, no cap. ⭐

💜 ARGUMENTS 💜

  • adapter — Pointer to the adapter structure. It's giving "main character energy" — everything routes through her. 👑
  • addr — Address of the register. Where we're reading from, iykyk. 📍
  • data — Pointer to the read data. This is where the bytes land, so pls make sure it points somewhere real. 🫶
  • count — Number of multiple bytes to be read. Yes bestie, count of multiple bytes — say it with me. 🌈

🔥 RETURN 🔥

  • 0 on success — slay, we ate. ✨
  • -1 on failure — not slay, we're crying. 😭

🦋 SEE ALSO 🦋

Kernel file: ./drivers/net/wireless/rsi/rsi_91x_sdio.c — go read the source, it's right there, be nosy. 🧚

And the whole friend group, fr fr:

💀 friendly reminder: the return is 0 for success and -1 for failure, that's it, don't overthink it. Also count is u16 and addr is u32, keep those types cute and correct.

k bye bestie, go read some registers 💖✨🎀
