💅 typec_match_altmode(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is typec_match_altmode, and she's filed under section 9 of the manual, literally. Let's get into it 🫶

🦋 NAME 🦋

typec_match_altmode — match SVID and mode to an array of alternate modes 💖

no cap, that's the whole vibe: you got a pile of alternate modes, you got an SVID and a mode, and you want to see who matches.

✨ SYNOPSIS ✨

struct typec_altmode * typec_match_altmode (struct typec_altmode
**altmodes , size_t n , u16 svid , u8 mode );

look at her go 😭 she takes a pointer-to-pointer, a size, a u16 and a u8, and hands you back a struct typec_altmode *. iconic.

🎀 ARGUMENTS 🎀

  • altmodes — the array of alternate modes, bestie. it's the lineup 👑
  • n — how many elements are in that array, or -1 for NULL terminated arrays 🌸 (yes, negative one as a size_t, that's just how she rolls, don't @ me)
  • svid — the Standard or Vendor ID you're matching with 🔍
  • mode — the mode you're matching with ⭐

💜 DESCRIPTION 💜

she returns a pointer to an alternate mode with an SVID matching svid, or NULL when no match is found 💀

that's it, that's the whole function. tiny, focused, main character energy — she knows what she's about 🧚

btw the docs say SVID matching — that's the promise being made here, iykyk 👀
