zstd_get_cparams(9)

💅 zstd_get_cparams(9) — kernel API manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little function called zstd_get_cparams and honestly? it's giving "personal shopper for compression settings." 🛍️ Let's get into it.

---

🌸 NAME 🌸

zstd_get_cparams — returns zstd_compression_parameters for the selected level 🎀

Like, you tell it a level, and it goes and fetches you the matching zstd_compression_parameters. That's the whole vibe. No cap.

---

✨ SYNOPSIS ✨

zstd_compression_parameters zstd_get_cparams (int level , unsigned long long estimated_src_size , size_t dict_size );

That's the whole signature, copy it exactly, don't @ me. 💅

---

🦋 ARGUMENTS 🦋

• level — the compression level. yes literally just that. the level. of compression. 🫶
• estimated_src_size — the estimated source size you're about to compress, or 0 if you genuinely have no idea. it's okay, nobody knows their size upfront sometimes 😭
• dict_size — the dictionary size. that's it. that's the arg. 🎀

---

👑 RETURN 👑

It hands you back the selected zstd_compression_parameters. icon behaviour, honestly. ⭐

💀 friendly reminder that every single one of those is a different function, so don't go merging them in your head just because the list is long. iykyk.
