💖 acpi_dev_uid_to_integer(9) 💖

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding time now 🫶

✨ NAME ✨

acpi_dev_uid_to_integer — treat ACPI device _UID as integer

like, it takes the _UID thing and is all "you're a number now bestie" 🔥

🌸 SYNOPSIS 🌸

int acpi_dev_uid_to_integer (struct acpi_device *adev , u64 *integer );

literally the whole signature, no cap. two args, one int coming back at you 💅

🎀 ARGUMENTS 🎀

  • adev — the ACPI device you're grabbing the _UID from 👑
  • integer — the output buffer where the integer lands, that's its whole job 🫶

🦋 DESCRIPTION 🦋

so the vibe here is: it considers _UID as integer and converts it to integer. that's it, that's the move. iconic honestly ✨

and it returns 0 on success, or negative error code otherwise. so like, check your return value, bestie, don't just assume 😭

💜 SEE ALSO 💜
