dvb_vb2_fill_buffer(9)

💅 dvb_vb2_fill_buffer (9) — Kernel API Manual, bestie edition 🎀

okay so this is a page straight out of the Kernel API Manual, and today's main character is dvb_vb2_fill_buffer(9). it's a lil function that, like... fills a VB2 buffer. that's the whole vibe. let's get into it ✨

---

🌸 NAME 🌸

dvb_vb2_fill_buffer — fills a VB2 buffer 🫶

---

✨ SYNOPSIS ✨

int dvb_vb2_fill_buffer (struct dvb_vb2_ctx *ctx , const unsigned char
       *src , int len , enum dmx_buffer_flags *buffer_flags , bool flush );

so it returns an int, and it takes five whole arguments. she's thorough. we respect that 💅

---

🔥 ARGUMENTS 🔥

• ctx — the control struct for the VB2 handler. like, the whole operation's home base 🏠
• src — the place where the data is stored. this is where we're copying from, bestie 👀
• len — number of bytes to be copied from src. yes, the byte count, we love a specific number 🔢
• buffer_flags — pointer to buffer flags as defined by enum dmx_buffer_flags. and listen — this one can be NULL. no cap, it's allowed 🙈
• flush — flush the buffer, even if it isn't full. like, she doesn't have to be at capacity to get emptied, okay?? 💀

lowkey reminder: buffer_flags being NULL-able is genuinely fine, it's in the docs — don't panic 🧚
