VAR V4L2_TYPE_NAMES(9)

✨ var v4l2_type_names(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel, we're in the big leagues now — and it's about one little helper array that's doing the absolute most for your debug output. let's get into it 💅

---

🌸 NAME 🌸

v4l2_type_names — a helper array that maps V4L2_BUF_TYPE_* over to strings. literally a glow-up for your buffer type numbers 🎀

---

✨ SYNOPSIS ✨

extern const char *v4l2_type_names[];

that's it. that's the whole declaration. iconic, honestly. no arguments, no return value, just a const char * array living its truth 🦋

---

💖 Description 💖

so here's the vibe: when you're printing debug messages, it's genuinely nice to output the V4L2 buffer type number alongside a name that actually represents its content. like, yes, the number is fine, but a name said what it said. this array is the one serving that translation, no cap 🔥

💀 reminder bestie: keep v4l2_type_names spelled exactly like that when you're grepping, and keep that extern const char * in your head — const-correctness is main character energy and we don't fumble it 🙈

aaaand that's the page! 🧚 this little beauty lives in ./include/media, from the October 2026 era, and it's filed under var v4l2_type_names(9) — go forth and print pretty debug messages, you absolute slay ⭐💜
