w1_netlink_send_error(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual entry for w1_netlink_send_error(9) — yes the title is the same as the function name, we love a self-titled icon 👑

🎀 NAME 🎀

w1_netlink_send_error — sends the error message now. like, immediately. no queueing, no waiting, we are NOT doing the whole song and dance today 💅

🦋 SYNOPSIS 🦋

void w1_netlink_send_error (struct cn_msg *cn , struct w1_netlink_msg
*msg , int portid , int error );

literally that's the whole signature, copy it exactly bestie, don't be creative with it 🫶

🌸 ARGUMENTS 🌸

  • cn — the original cn_msg. yeah, the one you already had. we're reusing it, sustainability queen 🌱
  • msg — the original w1_netlink_msg. also the one you already had ✨
  • portid — where to send it. that's the destination, keep track of it 💌
  • error — the error status. the whole reason we're here 😭

💜 DESCRIPTION 💜

Use this when a block isn't available to queue the message to, and cn and msg might not be contiguous.

heads up bestie: that "might not be contiguous" part is doing a LOT of heavy lifting — the function is built to cope with cn and msg not sitting next to each other in memory, which is exactly why you use this one instead of the queue-y version. ikyk 👀
