✨ NAME ✨

vpif_enum_fmt_vid_cap — the ENUM_FMT handler 🎬 that's literally the whole vibe, she handles the ENUM_FMT ioctl, periodt.

---

🌸 SYNOPSIS 🌸

int vpif_enum_fmt_vid_cap (struct file *file , void *priv , struct

🦋 ARGUMENTS 🦋

okay bestie, let's meet the cast 💅

• file — file ptr. literally just a pointer to the file. that's her.
