💅 v4l2_event_unsubscribe(9) 💅

okay so this is a page from the Kernel API Manual — yes, the actual kernel, we're in the big leagues now bestie 🎀 — and it's all about unsubscribing to an event. Like leaving a group chat but for V4L2 events. No drama, just cleanup. ✨

🌸 NAME 🌸

v4l2_event_unsubscribe — unsubscribes to an event 🫶

---

✨ SYNOPSIS ✨

int v4l2_event_unsubscribe (struct v4l2_fh *fh , const struct
v4l2_event_subscription *sub );

that's the whole vibe, honestly — takes two pointers, returns an int. slay. 💅

---

🦋 ARGUMENTS 🦋

• fh — pointer to struct v4l2_fh. literally just a pointer to a struct v4l2_fh, that's the whole thing, no cap. 🍓
• sub — pointer to struct v4l2_event_subscription. also exactly what it says on the tin: a pointer to a struct v4l2_event_subscription. iconic. 🌟
