v4l2_device_get(9)

💖 v4l2_device_get(9) — like, the Kernel API Manual page you actually want to read 💖

okay so bestie, gather round 🫶 this little icon lives in the Kernel API Manual, and its whole personality is: get a V4L2 device reference. that's it. that's the girl. ✨

✨ NAME ✨

v4l2_device_get — gets a V4L2 device reference 🎀

🌸 SYNOPSIS 🌸

void v4l2_device_get (struct v4l2_device *v4l2_dev );

no cap, that's the whole signature. short king. 👑

🦋 ARGUMENTS 🦋

• v4l2_dev — pointer to struct v4l2_device. literally just a pointer to the device struct, bestie. that's the vibe. 💅

💜 DESCRIPTION 💜

okay so here's the tea ☕ — this is an ancillary routine, meaning it's a little helper doing side-quest work for the main character. its one job? increment the usage for the struct v4l2_device pointed by v4l2_dev. that's it. it bumps the usage and dips. 🙈

not me being obsessed with how simple that is. increment the usage, periodt. no return value, no drama, no error codes — it's void, so it's giving silent-but-competent energy. 🔥

heads up: it only does what's written here — incrementing usage for the struct v4l2_device that v4l2_dev points to. don't go inventing extra lore. 💀
