💅 pdc_iodc_print(9) — Kernel API Manual

okay so bestie, buckle up: this is pdc_iodc_print from the Kernel API Manual, section 9, and it's literally the function that makes your console actually print stuff through IODC. no cap. ✨

🌸 NAME 🌸

pdc_iodc_print — console print using IODC. that's the whole vibe. 🖨️💖

✨ SYNOPSIS ✨

int pdc_iodc_print (const unsigned char *str , unsigned count );

like. it returns an int, it takes a const unsigned char * and an unsigned count. simple. iconic. periodt. 👑

🎀 ARGUMENTS 🎀

  • str — the string you wanna output. that's it, that's the payload 🫶
  • count — the length of str. yes you have to tell it how long. it's not gonna guess, bestie 💀

🦋 DESCRIPTION 🦋

okay so here's the tea, and it's lowkey important: only these special chars are architected for console IODC io — BEL, BS, CR, and LF. that's the whole approved list, no cap.

everything else? just passed through. it doesn't get any special treatment, it just vibes on through 🌈

and since the 0. console requires CR+LF to perform a 'newline', we translate "0 to " — yes that's exactly how it's written on the page, i'm not fixing it, i'm just reporting it fr fr 🙈

ngl, that last sentence is giving "the manpage had a little formatting moment." copying it exactly because the facts stay the facts. 💀
