v4l2_async_c...ction_unique(9)

💅 v4l2_async_connection_unique 💅

okay bestie, this one's from the Kernel API Manual and it's honestly a little cutie — short, sweet, and gives you exactly one thing 🎀

---

🌸 NAME 🌸

v4l2_async_connection_unique — return a unique &struct v4l2_async_connection for a sub-device ✨

---

🦋 SYNOPSIS 🦋

struct v4l2_async_connection * v4l2_async_connection_unique (struct
v4l2_subdev *sd );

---

💖 ARGUMENTS 💖

• sd — the sub-device 👑 (that's it, that's the whole argument list, she's low maintenance)

---

✨ DESCRIPTION ✨

so the way this works is: you hand her a sub-device and she returns an async connection for it — but only when there is a single one. one (1) connection. a solitary little guy. no multiples, no chaos, just the one 🫶

like if there's exactly one async connection for that sub-device, slay, here you go. that's the whole vibe check 🌈
