zstd_cstream...kspace_bound(9)

✨ zstd_cstream...kspace_bound(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is, like, such a specific little function 🎀 — it tells you how much memory you gotta set aside before you can even think about spinning up a zstd compression stream. no cap, it's the "how big is the venue before we book the band" of kernel APIs 💅

---

🌸 NAME 🌸

zstd_cstream_workspace_bound — the amount of memory you need to initialize a zstd_cstream ✨

---

🦋 SYNOPSIS 🦋

size_t zstd_cstream_workspace_bound (const zstd_compression_parameters *cparams );

---

💖 ARGUMENTS 💖

• cparams — the compression parameters that are gonna be used for compression 👑 like, these are your settings, your vibe, your whole compression personality. you hand 'em over and it does the math 🧮

---

🌈 RETURN 🌈

a lower bound on the size of the workspace that gets passed to zstd_init_cstream 💫

lowkey important: it's a lower bound, not an exact number — so don't go thinking this is the whole story, it's the floor, not the ceiling 🙈
