CK_HT_COUNT(3)

💖 CK_HT_COUNT 💖

okay bestie, welcome to the CK_HT_COUNT(3) page, and yes it's from the Concurrency Kit era of your life now, we're doing this 🫶

✨ NAME ✨

ck_ht_count — return count of key-value pairs in hash table

📚 LIBRARY 📚

Concurrency Kit — link it with libck, so like -lck on your compile line. yes literally that's it. 🎀

🌸 SYNOPSIS 🌸

#include <ck_ht.h>

uint64_t
ck_ht_count(ck_ht_t *ht);

🦋 DESCRIPTION 🦋

okay so here's the vibe: ck_ht_count() hands you back the number of entries chillin' in the hash table that the ht argument points at. that's the whole thing. it counts your little key-value pairs and returns them as a uint64_t. iconic behavior honestly 💅

but listen, and this part is NOT optional — this function may only be called without the presence of concurrent write operations. like, no writers doing their writer thing while you're counting. read-only energy only. do not test her. 😭

💀 ERRORS 💀

if ht has not been initialized, the behavior is undefined. not "oopsie" undefined, like actual undefined behavior, the spooky kind. initialize your table first, bestie, please, i'm begging 🙈
