usb_power_de..._link_device(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual ✨ this one is a little function from the usb_power_de..._link_device(9) page and honestly? it's giving glue code in the best way possible. it doesn't do a million things — it does one thing and it slays at it 💅 let's get into it.

🌸 NAME 🌸

usb_power_delivery_link_device — link a device to its USB PD object 🫶

like, you've got a device, you've got a USB Power Delivery instance, and this function is the matchmaker that finally introduces them 😭💖

✨ SYNOPSIS ✨

int usb_power_delivery_link_device (struct usb_power_delivery *pd ,
struct device *dev );

it returns an int btw, so keep an eye on that 👀 (we're not told what the return values mean on this page, so don't come for me — the manpage doesn't say, so I don't say either 🙈)

🎀 ARGUMENTS 🎀

  • pd — the USB PD instance 💫 this is the main character of the pair, the thing the symlink is gonna point at.
  • dev — the device 🦋 this is the one getting a brand-new symlink attached to it. lucky them.

👑 DESCRIPTION 👑

okay so here's the whole vibe: this function can be used to create a symlink named "usb_power_delivery" for dev that points to pd.

that's it. that's the function. one symlink, zero drama 🎀 you call it, and dev gets a friend called usb_power_delivery who is literally just a pointer over to pd. cute, iconic, no cap ✨

lowkey important: the symlink is named exactly "usb_power_delivery" — not "usb-pd", not "pd", not whatever your heart tells you. keep it exact bestie 💅
