zstd_end_stream(9)

🎀 zstd_end_stream(9) 🎀

okay bestie, welcome to the Kernel API Manual page for zstd_end_stream(9). It’s giving “last call at the compression party” energy, and honestly? Iconic. 💅

---

✨ NAME ✨

zstd_end_stream — flush internal buffers into output and end the frame. That’s the whole vibe: get the internal buffers out into output, then wrap up the frame. 🎬

---

🦋 SYNOPSIS 🦋

size_t zstd_end_stream (zstd_cstream *cstream , zstd_out_buffer *output
);

---

🌸 ARGUMENTS 🌸

• cstream — the zstd streaming compression context. This is the context you’re working with, main character energy. 👑
• output — destination buffer. output->pos is updated to indicate how much compressed data was written. Yes, it tracks the progress for you. 🫶

---

💖 DESCRIPTION 💖

zstd_end_stream is not a one-and-done bestie. It must be called until it returns 0, meaning all the data has been flushed and the frame epilogue has been written. So keep calling it, and when you finally see that 0, that’s the “we’re done, frame epilogue written” moment. ✨

---

🔥 RETURN 🔥

Returns the number of bytes still present within internal buffers, or an error. You can check that error using zstd_is_error. So if the number isn’t 0 and it’s not an error, there’s still stuff in the internal buffers — keep going. 👀
