xcan_write_reg_be(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xcan_write_reg_be(9) — like, the big endian register-writer ✨

okay so bestie, welcome to the xcan_write_reg_be(9) page from the Kernel API Manual 🎀 this is the group chat where kernel functions get their lore explained, and today's main character is a tiny little void function that writes a value into a device register. big endian style. no cap 💖

✨ NAME ✨

xcan_write_reg_be — Write a value to the device register big endian 🦋

like... that's literally her job description and she's slaying it.

🌸 SYNOPSIS 🌸

void xcan_write_reg_be (const struct xcan_priv *priv , enum xcan_reg reg
, u32 val );

it returns void btw — no return value, no drama, she just does the thing and ghosts 💅

💖 ARGUMENTS 💖

three besties walk into a function:

  • priv — the Driver private data structure 🫶 like, the driver's little bag of secrets
  • reg — Register offset ⭐ where in the register map we're going
  • val — Value to write at the Register offset ✨ the actual payload, the moment, the icon

🔥 DESCRIPTION 🔥

Write data to the paricular CAN register 🔥

that's it. that's the whole vibe. you hand her priv, you tell her which reg (offset), and you give her a val, and she goes and writes that data into the paricular CAN register. yes bestie, "paricular" is spelled exactly like that in the source and we are respecting the original's choices 🙈 periodt.

no return value. no error checking mentioned. she is a humble little side-effect and we bow 👑

like, that's the whole roster 😭 they're all in their (9) era and honestly? iconic.

ngl if you're looking for the little-endian version, don't panic — xcan_write_reg_le(9) is right there in the list above. opposites attract bestie 💜

that's the whole page!! hope this helped, mwah 🎀

source line says ./drivers/net/can, it's dated October 2026, and the page answers to xcan_write_reg_be(9) — catch you in the next manpage, bestie 🌈💖✨
