v4l2_ctrl_new_std(9)

📦 version 7.3.1, in nixpkgs unstable

💅 v4l2_ctrl_new_std(9) — like, the whole glow-up guide 🎀

okay bestie, welcome to the Kernel API Manual entry for v4l2_ctrl_new_std — yes that's the function name, no we're not shortening it, it's iconic and it knows it ✨

🌸 NAME 🌸

v4l2_ctrl_new_std — allocates and initializes a brand-new standard V4L2 non-menu control. that's it, that's the whole vibe. non-menu. write that down, it comes back later 👀

🦋 SYNOPSIS 🦋

struct v4l2_ctrl * v4l2_ctrl_new_std (struct v4l2_ctrl_handler *hdl ,
const struct v4l2_ctrl_ops *ops , u32 id , s64 min , s64 max , u64 step
, s64 def );

look at her. seven args. serving thorough 💅

🍓 ARGUMENTS 🍓

  • hdl — the control handler. the main character, the container, the group chat admin 🫶
  • ops — the control ops. the behavior pack, the personality ✨
  • id — the control ID. her legal name, no nicknames 🔥
  • min — the control's minimum value. the floor, the bare minimum (respectfully) 🌸
  • max — the control's maximum value. the ceiling, the limit, the "we don't go higher than this" 📈
  • step — the control's step value. yes the original really has no period there, and honestly? she doesn't need one 🎀
  • def — the control's default value. where she starts out in life 💖

💜 DESCRIPTION 💜

okay so, the actual lore 🧚

if the v4l2_ctrl struct could not be allocated, or the control ID is not known, then NULL is returned and hdl->error gets set to the appropriate error code (if it wasn't set already). so like, the error lands somewhere, don't panic, just check it 😭

also, if id refers to a menu control, this function will return NULL. hard pass. not her department. 🚫

use v4l2_ctrl_new_std_menu when you're adding menu controls — that's the correct sister function, go bother her 💅

🌈 SEE ALSO 🌈

the full squad, in order, exactly as listed, no one left behind 🫶 — and yes it starts with the kernel file itself:
