pvr_stream_process_1(9)

👑 pvr_stream_process_1 — NAME, but make it a vibe

okay so bestie, welcome to the Kernel API Manual ✨ — this one is pvr_stream_process_1(9) and it's literally the "process exactly one stream and fill in the destination structure" of your dreams 💅

pvr_stream_process_1 — process a single stream and fill destination structure 🫶

---

✨ SYNOPSIS ✨

int pvr_stream_process_1 (struct pvr_device *pvr_dev , const struct
pvr_stream_def *stream_def , u32 nr_entries , u8 *stream , u32
stream_offset , u32 stream_size , u8 *dest , u32 dest_size , u32
*stream_offset_out );

no cap, that's the whole signature, don't touch it 🔥

🎀 ARGUMENTS 🎀

mkay so here's the receipts on every single param, we are NOT skipping any, periodt:

• pvr_dev — Device pointer. that's the device, icon behavior 🦋
• stream_def — Stream definition. yep, the definition of the stream 📖
• nr_entries — Number of entries in stream_def. count 'em 👑
• stream — Pointer to stream. it's giving "here's the stream" 🌊
• stream_offset — Starting offset within stream. like where you start reading, ikyk 🎯
• stream_size — Size of input stream, in bytes. yes, bytes, not vibes 💀
• dest — Pointer to destination structure. where the good stuff goes 🍓
• dest_size — Size of destination structure. also bytes-adjacent energy, it's the size bestie 🌸
• stream_offset_out — Pointer to variable to write updated stream offset to. May be NULL. lowkey important: it literally may be NULL, so don't panic 🙈

---

⭐ RETURN ⭐

what does it hand back to you? so glad you asked:

• 0 on success, or
• -EINVAL on malformed stream.

that's it, that's the tea ☕ malformed stream = -EINVAL, no notes 💅

ok tiny reminder bestie: only one stream gets processed here. one. single. stream. the multi-stream one is a whole other manpage, don't come for me 😭
