v4l2_find_nearest_size(9)

🦋 v4l2_find_nearest_size(9) 🦋

okay so we are in the Kernel API Manual, and today’s main character is v4l2_find_nearest_size(9) — the little helper that goes “say less, I’ll find the closest size for you.” 💅

---

✨ NAME ✨

v4l2_find_nearest_size — find the nearest size among a discrete set of resolutions contained in an array of a driver specific struct. matchmaker behavior, honestly 💖

---

🌸 SYNOPSIS 🌸

v4l2_find_nearest_size (array , array_size , width_field , height_field
, width , height );

---

🎀 ARGUMENTS 🎀

• array — a driver specific array of image sizes 🫶
• array_size — the length of the driver specific array of image sizes
• width_field — the name of the width field in the driver specific struct
• height_field — the name of the height field in the driver specific struct
• width — desired width
• height — desired height

---

💜 DESCRIPTION 💜

So what it does is find the closest resolution to minimize the width and height differences between what requested and the supported resolutions. it’s giving “close enough, but make it precise” energy ✨

The size of the width and height fields in the driver specific must equal to that of u32, i.e. four bytes. four bytes, no cap — don’t get cute with the field size 💀

Returns the best match or NULL if the length of the array is zero. yes bestie, zero length means NULL; that’s the vibe check 😭
