zstd_init_cctx(9)

💅 zstd_init_cctx

okay so bestie, welcome to the zstd_init_cctx(9) page — it's from the Kernel API Manual and it's literally your cheat code for birthing a zstd compression context 🎀

---

✨ NAME ✨

zstd_init_cctx — initialize a zstd compression context 🫶

---

🌸 SYNOPSIS 🌸

zstd_cctx * zstd_init_cctx (void *workspace , size_t workspace_size );

---

💖 ARGUMENTS 💖

• workspace — this is the workspace you're gonna emplace the context into. and like, important: it must outlive the returned context. no cap. if your workspace ghosts before your context does, that's giving undefined chaos 💀
• workspace_size — the size of workspace. use zstd_cctx_workspace_bound to figure out how big the workspace has to be. don't just vibe-guess the number, bestie 🙈

---

⭐ RETURN ⭐

you get a zstd compression context back 🎉... or NULL on error 😭 (so yeah, check it, always check it).
