📦 version 7.3.1, in nixpkgs unstable

💅 hvc_iucv_alloc(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the hvc_iucv_alloc(9) page and it's literally the origin story of a brand-new struct hvc_iucv_private instance ✨ like it's giving "birth of an icon" energy and honestly? obsessed.

🌸 NAME 🌸

hvc_iucv_alloc — allocates a new struct hvc_iucv_private instance 🎀

no cap, that's the whole vibe of this function. it makes one (1) private instance and it slays.

✨ SYNOPSIS ✨

int hvc_iucv_alloc (int id , unsigned int is_console );

she takes two arguments and returns an int, periodt 💅

🦋 ARGUMENTS 🦋

  • id — this is the hvc_iucv_table index 🗂️ like, which slot in the table this instance is gonna live in. you pick the address, she moves in.
  • is_console — a flag telling everyone whether this instance is used as the Linux console 🖥️👑 it's a yes/no situation and yes, it matters.

💖 DESCRIPTION 💖

so here's the tea ☕ — this function allocates a new hvc_iucv_private structure and stores that instance in hvc_iucv_table at index id. that's it, that's the whole job, and she does it beautifully 🫶

return value check, because we care about results: it returns 0 on success; otherwise non-zero 😭 (yes, non-zero means something went sideways — keep an eye on it, bestie).

ngl there's not a lot of drama here, and that's exactly why we love her. alloc, store, report. main character energy with zero messy subplot 💀

🔥 SEE ALSO 🔥

the kernel file lives at ./drivers/tty/hvc/hvc_iucv.c and honestly the whole friend group is here 🌈 — go say hi to:
