✨ dvb_vb2_reqbufs ✨

okay bestie so this is dvb_vb2_reqbufs from the Kernel API Manual — it's literally just a little wrapper around vb2_core_reqbufs() that handles Digital TV buffers for you 🎀

---

💖 NAME 💖

dvb_vb2_reqbufs — the wrapper to vb2_core_reqbufs() for Digital TV buffer handling. that's it, that's the vibe ✨

---

🌸 SYNOPSIS 🌸

int dvb_vb2_reqbufs (struct dvb_vb2_ctx *ctx , struct dmx_requestbuffers
*req );

---

🦋 ARGUMENTS 🦋

• ctx — the control struct for the VB2 handler. it's giving main character energy 👑
• req — a struct dmx_requestbuffers passed from userspace so we can handle DMX_REQBUFS. coming straight from the user, no cap 💅

---

🌈 DESCRIPTION 🌈

So like, this is how you initiate streaming — you request a number of buffers, periodt. it's also the thing you use to free previously requested buffers, and the way you do that is req->count is zero. yep, zero means free it. lowkey iconic 🫶
