✨ __iucv_call_b2f0 ✨

okay so bestie, welcome to section 9 of the Kernel API Manual — this is the page for __iucv_call_b2f0, and yes it's a double-underscore name, she's lowkey mysterious like that 💅

🌸 NAME 🌸

__iucv_call_b2f0 — calls CP to execute IUCV commands.

like, that's the whole vibe. you hand CP a command, CP does the thing. iconic behavior fr fr 👑

🦋 SYNOPSIS 🦋

int __iucv_call_b2f0 (int command , union iucv_param *parm );

that's it, that's the whole signature. int in, int out, one union pointer in the middle. slay 🎀

💖 ARGUMENTS 💖

  • command — the identifier of the IUCV call to CP. basically you're telling CP which command you want it to run. no cap, this is the important part 🫶
  • parm — a pointer to a struct iucv_parm block. yes, the synopsis says union iucv_param and the argument description says struct iucv_parm — that's literally what the page says, so we're keeping both exactly as-is, don't come for me 😭

⭐ RETURN ⭐

this function returns the result of the CP IUCV call. so like, whatever CP says back, that's what you get. that's the whole return value, bestie 💜
