dvb_vb2_init(9)

💅 dvb_vb2_init(9) — the Kernel API Manual moment

okay bestie, so this is dvb_vb2_init from the Linux Kernel API Manual, and it's literally the glow-up ritual for a VB2 handler ✨ — it initializes VB2 handler, that's the whole vibe. Come set it up with me 🫶

✨ SYNOPSIS ✨

int dvb_vb2_init (struct dvb_vb2_ctx *ctx , const char *name , struct mutex *mutex , int non_blocking );

like yes, it returns an int, and yes it takes four things, we'll get to them 💖

🎀 ARGUMENTS 🎀

• ctx — the control struct for the VB2 handler. it's giving main character energy, this is the thing you're setting up 👑
• name — the name for the VB2 handler. give it a name, let it have an identity 🦋
• mutex — pointer to the mutex that serializes vb2 ioctls. no cap, this is the bouncer keeping the ioctls from all talking at once 🙈
• non_blocking — if it's not zero, it means the device is at non-blocking mode. zero? blocking. not zero? not blocking. simple math, slay 💅

lowkey the cutest part: this whole page lives under ./include/media, and it's dated October 2026 — a little time capsule from the future bestie 🌈
