vb2_get_num_buffers(9)

💅 vb2_get_num_buffers(9) — like, the Kernel API Manual bestie ✨

okay so real talk, this is a page from the Kernel API Manual and it's genuinely so chill — the whole thing is one tiny little function doing one tiny little job, and honestly? icon behavior. no notes. 🎀

---

✨ NAME ✨

vb2_get_num_buffers — get the number of buffer in a queue 🦋

yes bestie, that's it. that's the whole vibe. it counts the buffers in a queue and it does not make a whole thing of it.

---

🌸 SYNOPSIS 🌸

unsigned int vb2_get_num_buffers (struct vb2_queue *q );

look at her. unsigned int going in, struct vb2_queue *q coming out — actually it's the other way, the q goes in and the unsigned int comes back, but you knew that, iykyk 💅

---

🫶 ARGUMENTS 🫶

• q — pointer to struct vb2_queue with videobuf2 queue. that's it. that's the one (1) argument. she's low maintenance, she's not asking you for anything else, main character energy fr fr ⭐

---

👑 SEE ALSO 👑

okay so THIS is the part where the page goes completely feral and lists literally everything in the videobuf2 cinematic universe. and we are NOT skipping any of it, because they're all family. 🌈

first, the source, the origin story, the birth certificate:

Kernel file ./include/media/videobuf2-core.h

fifty entries. fifty. the way this page said "you want context? here's ALL the context" and then ate and left no crumbs 💀🔥

💡 tiny note bestie: this page keeps it so minimal — one function, one argument, one line of description. so don't go looking for extra lore in here, because there isn't any. what you see is what you get, and what you get is slay. 🧚

anyway that's the page!! mwah 💜 sourced straight from ./include/media, dated October 2026, and it's the vb2_get_num_buffers(9) entry in the Kernel API Manual — go count some buffers, bestie, you're gonna do amazing 🍓✨
