CK_HT_HASH(3)

💖 CK_HT_HASH(3) — ck_ht_hash 💖

okay so bestie, welcome to the ck_ht_hash page of the Concurrency Kit manual (that's section 3 of the man pages, iykyk) 🦋

📚 LIBRARY

Concurrency Kit — link it with libck, aka -lck. That's the whole vibe. ✨

🎀 SYNOPSIS

#include <ck_ht.h>

void
ck_ht_hash(ck_ht_hash_t *h, ck_ht_t *ht, const void *key,
    uint16_t key_length);

✨ DESCRIPTION ✨

so basically, ck_ht_hash() is the girl who does the math so you don't have to 💅

She generates a hash value, and she tucks it right into the object that h points to. That value? It's valid for use in the hash table that ht points to, for the key you hand her — and that key is a bytestring type thing, specified by the key argument. 🌸

How long is that key, you ask? That's literally what key_length is for. She needs to know how many bytes she's working with, no cap. 🫶

🫧 RETURN VALUES

ck_ht_hash() has no return value. She gives you nothing back — she just does the thing and fills in h. Silent queen behavior, honestly. 👑

💀 ERRORS

Behavior is undefined if key is NULL or if ht is uninitialized. 😭

fr fr, do NOT do this. Undefined behavior is not the moment. Vibe check your pointers first, bestie. 🚨
