💖 zstd_free_dctx 💖

okay so bestie, welcome to the zstd_free_dctx page in the Kernel API Manual ✨ this one is literally “Free decompression context” and it’s giving clean-and-simple main character energy 💅 no cap.

✨ SYNOPSIS ✨

here’s the exact little signature, copy it like your life depends on it fr fr:

size_t zstd_free_dctx (zstd_dctx *dctx );

🫶 ARGUMENTS 🫶

• dctx — Pointer to decompression context. that’s the whole vibe: a pointer, periodt 🎀

🔥 RETURN 🔥

• Always 0. 💖 no cap, every single time. not a maybe, not a sometimes — always.
