🌸 video_set_drvdata(9) 🌸

okay so bestie, welcome to the Kernel API Manual — yes we're in kernel land today, and no, it's not scary, i promise 🫶 this one's a tiny little function that just... sets a pointer. that's it. that's the whole vibe.

---

✨ NAME ✨

video_set_drvdata — sets private data from &struct video_device.

literally just attaches your own private data pointer to a video device. iconic, low-effort, does exactly what it says on the tin 💅

---

🎀 SYNOPSIS 🎀

void video_set_drvdata (struct video_device *vdev , void *data );

no return value, no drama, no error paths. she just does it ✨

---

💖 ARGUMENTS 💖

• vdev — pointer to struct video_device. this is the video device you're stuffing your data into, bestie 🎥
• data — private data pointer. your very own void * of mystery and intrigue — whatever you hand over is what gets stored 🌈

ngl this page is short because the function is short — set the data, get the data later with video_get_drvdata(9), and go live your life 💜
