📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

pdc_iodc_getc — read a character (non-blocking) from the PDC console ✨

okay so real talk, this is a page from the Kernel API Manual, and it's tiny but iconic — it's the little firmware call that peeks at your PDC console and grabs a key if there's one waiting. no cap, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

int pdc_iodc_getc (void );

🌸 ARGUMENTS 🌸

  • void — no arguments. that's it. nothing to pass, nothing to worry about, bestie. an empty handbag, but make it C 🫶

⭐ DESCRIPTION ⭐

Read a character (non-blocking) from the PDC console — and the non-blocking part is the main character here. it does not sit there waiting for you to press something. it checks, and if there's no key present it just returns -1 and moves on with its life 💅

so like:

  • key present? you get the character 💖
  • key not present? you get -1, no drama, no hang, no waiting around like a text back 😭

🔥 SEE ALSO 🔥

the whole friend group lives in the kernel file ./arch/parisc/kernel/firmware.c — here's the full roster, no one left out 👑

and that's the whole page, bestie — short, sweet, and it's giving "one job, done non-blockingly" 💜

sign-off szn: this lil masterpiece ships from ./arch/parisc/kernel and the page is dated October 2026. screenshot it, pin it, frame it 🎀✨👑
