📦 version 7.3.1, in nixpkgs unstable

💅 awcc_op_get_resource_id 💅

okay so this is a page out of the Kernel API Manual — yes, the kernel has its own manual, and yes, it's iconically dry, so let me be your tour guide bestie 🫶 We're looking at awcc_op_get_resource_id, a lil function that goes and fetches you a resource ID. Let's get into it ✨

🌸 NAME 🌸

awcc_op_get_resource_id — Get the resource ID at a given index

Like, you give it an index, it gives you back the ID. Simple. Elegant. Ate. 💅

✨ SYNOPSIS ✨

int awcc_op_get_resource_id (struct wmi_device *wdev , u8 index , u8
*out );

That's the whole signature, no cap. Returns an int, takes a struct wmi_device *, a u8 index, and a u8 pointer for the output 🎀

🦋 ARGUMENTS 🦋

  • wdev — the AWCC WMI device. That's your main character right there, the thing you're talking to 👑
  • index — the Index. Yes bestie, just "Index." That's the whole description. Iconic minimalism honestly 💀
  • out — Value returned by the WMI call. This is where the answer lands, so point it somewhere real 🙈

💖 DESCRIPTION 💖

So here's the vibe: Get the resource ID at a given index. That's the assignment, and it understood it. ✨

Resource IDs are listed in the following order:

  • Fan IDs
  • Sensor IDs
  • Unknown IDs
  • Thermal Profile IDs

The way this ordering matters is lowkey important — the index you pass is walking down that list, so the order is the whole map, iykyk 🗺️

And if you wanna know the total number of IDs of a given type, you get that with AWCC_OP_GET_SYSTEM_DESCRIPTION. That's the move for "how many of these are there actually" energy 🌈

🔥 RETURN 🔥

  • 0 on success 🎉
  • -errno on failure 😭
fr fr check that return value, don't just assume it slayed 💀
