💅 rsi_sdio_host_intf_write_pkt — like, the whole page, bestie

Okay so this is from the Kernel API Manual, and it's about rsi_sdio_host_intf_write_pkt — yes that's a long name, no I will not be shortening it, it's giving "my wifi driver has a full government name" energy 💀

✨ NAME ✨

rsi_sdio_host_intf_write_pkt — this function writes the packet to device. That's it, that's the whole job. It takes your packet and yeets it at the device. Iconic behaviour honestly 🎀

🌸 SYNOPSIS 🌸

int rsi_sdio_host_intf_write_pkt (struct rsi_hw *adapter , u8 *pkt , u32
len );

Look at her. Three params, returns an int. Clean, simple, lowkey main character energy ⭐

🦋 ARGUMENTS 🦋

  • adapter — Pointer to the adapter structure. Your whole setup lives here, so like, don't pass garbage, bestie 🫶
  • pkt — Pointer to the data to be written on to the device. This is the actual payload, the moment, the content 💌
  • len — length of the data to be written on to the device. Gotta tell it how much, or it's just guessing, and we don't guess 🙈

🔥 RETURN 🔥

  • 0 on success — slay, it worked 💖
  • -1 on failure — not slay, something went wrong 😭
