💖 xxh64_digest(9) 💖

okay bestie, welcome to the Kernel API Manual entry for xxh64_digest(9) — it’s giving “tiny function, major hash energy” and honestly? obsessed. This one produces the current xxh64 hash, and yes, it ate. ✨

✨ SYNOPSIS ✨

uint64_t xxh64_digest (const struct xxh64_state *state );

🎀 ARGUMENTS 🎀

• state — your const struct xxh64_state *, bestie. It’s the state we’re using to produce the current xxh64 hash of this state. periodt. 💅

🦋 DESCRIPTION 🦋

So here’s the vibe: a hash value can be produced at any time. No waiting around, no “hold please,” none of that. 😌

And the cute part? It is still possible to keep inserting input into the hash state after a call to xxh64_digest, and then generate new hashes later on by calling xxh64_digest again. fr fr, it’s reusable like that. 🔥

👑 RETURN 👑

It returns the xxh64 hash stored in the state. That’s it, that’s the tea. 💖
