STRUCT DVB_BUFFER(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct dvb_buffer(9) 💖

okay so welcome to the Kernel API Manual bestie, we're talking about struct dvb_buffer today and honestly? it's giving "small but mighty." this is the video buffer information for v4l2, and yes i said information, periodt.

✨ NAME ✨

struct dvb_buffer — video buffer information for v4l2. that's it, that's the whole vibe. it holds the buffer info and it does it slayfully 💅

🌸 SYNOPSIS 🌸

here's the whole struct, copy it exactly bestie, no freestyling:

struct dvb_buffer {
    struct vb2_buffer       vb;
    struct list_head        list;
 };

look at that. two members, zero notes. iconic minimalism 🎀

🦋 Members 🦋

  • vb — the embedded struct vb2_buffer. it's living inside the struct, not a pointer to it — embedded fr fr, like a little buddy nestled in there 🫶
  • list — a struct list_head that's the list of struct dvb_buffer. it's a linked list situation, iykyk 🔥

👑 SEE ALSO 👑

okay this is the part where i hold your hand and walk you through the whole friend group, because this struct does not travel alone. all of these live in the Kernel file ./include/media/dvb_vb2.h:

that's the whole squad and you literally cannot skip a single one, they all pull up together 💀 the stream on/stream off pair is lowkey the main character energy of the list, and dvb_vb2_mmap(9) is that one friend who shows up last but ate anyway 🌈

ngl bestie, if you're poking around in here you're probably writing a DVB driver, so double-check you're reading the right header before you go changing anything — the file is ./include/media/dvb_vb2.h and that's non-negotiable 🙈

mwah, that's the page! this little honey came straight out of the ./include/media directory, dated October 2026, and it goes by struct dvb_buffer(9) 🍓💜 — go forth and buffer responsibly, bestie, you've got this ⭐🧚
