💅 vpif_update_std_info(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the glow-up of vpif_update_std_info, straight out of the Kernel API Manual (section 9, we love a kernel-doc moment 🎀). this one's short and sweet and honestly kind of a vibe.

🌸 NAME 🌸

vpif_update_std_info — update standard related info ✨ that's it, that's the whole job.

---

🦋 SYNOPSIS 🦋

int vpif_update_std_info (struct channel_obj *ch );

like, it returns an int, it takes one thing, we move 💅

---

🎀 ARGUMENTS 🎀

• ch — ptr to channel object 🫶 (yes, a pointer, yes, to a struct channel_obj, yes, it's the channel object, mwah)

---

💖 DESCRIPTION 💖

okay so here's the tea ☕: for a given standard that the application selected, this function updates the values in the device data structures. that's the whole arc. the standard gets picked, the device data structures get their little values refreshed, and everyone goes home happy. no cap, it's giving "small function, big responsibility" energy 👑
