dmi_get_bios_year(9)

📦 version 7.3.1, in nixpkgs unstable

💖 dmi_get_bios_year — the kernel API manual, bestie edition 💖

okay so real talk, this one is a little function from the Kernel API Manual and its whole personality is "grab a year out of the DMI_BIOS_DATE field." that's it. that's the gig. but she does it flawlessly, so we stan 🫶

✨ SYNOPSIS ✨

int dmi_get_bios_year (void );

like, no cap, that's the entire signature. she takes nothing, she returns an int. lowkey iconic of her 💅

🎀 ARGUMENTS 🎀

  • void — literally no arguments. zero. none. she doesn't need your input, bestie, she's got this on her own 🌸

🦋 DESCRIPTION 🦋

so here's the vibe check: on success she returns the year. like an actual year, pls respect her 🔥

but the plot thickens 😭 — she can also come back with:

  • -ENXIO if DMI is not selected. that's the "sorry babe, wrong room" error 💀
  • a different negative error code if the DMI field is not present or not parseable. translation: the field is missing, or it's giving nonsense and she can't read it 🙈
ngl, always error-check this one — if you just assume you got a year back you might be out here treating -ENXIO like it's 2024. it is not. it is a negative number. please check. 💀
