💅 rsi_usb_reg_write(9) — the Kernel API Manual page, bestie edition

okay so real talk: this is the manual page for rsi_usb_reg_write, straight out of the Kernel API Manual. yes the title is the function name AND the manual section, that's just how kernel girlies do it. anyway. it writes data into a register address. that's the whole vibe. let's get into it 🫶

✨ NAME ✨

rsi_usb_reg_write — this function writes the given data into the given register address. literally that's it, that's the job, and it does it flawlessly 💅

🌸 SYNOPSIS 🌸

int rsi_usb_reg_write (struct usb_device *usbdev , u32 reg , u32 value ,
u16 len );

no cap, that's the exact signature, spaces and all. copy it exactly if you're writing code, don't be out here "fixing" the punctuation bestie 😭

🎀 ARGUMENTS 🎀

  • usbdev — Pointer to the usb_device structure. yeah, the whole device. main character energy 👑
  • reg — Address of the register. like, where we're going 💖
  • value — Value to write. the actual payload, the moment, the reason we're all here ✨
  • len — Length of data to be written. gotta know how much we're sending, periodt.

🔥 RETURN 🔥

  • status — 0 on success, a negative error code on failure. so if you see 0, she ate. if it's negative, something went wrong and you should probably look at it 🙈
