hash_init(9)

💅 hash_init(9) 💅

okay bestie, welcome to the Kernel API Manual page for hash_init — the little init moment your hash table deserves 💖

🌸 NAME 🌸

hash_init — initialize a hash table ✨

🫶 SYNOPSIS 🫶

hash_init (hashtable );

🎀 ARGUMENTS 🎀

• hashtable — the hashtable to be initialized. That's the whole assignment, bestie 🫶

🦋 DESCRIPTION 🦋

It calculates the size of the hashtable from the given parameter — otherwise it's the same as hash_init_size 💅

Real talk: this has to be a macro, because HASH_BITS will not work on pointers since it calculates the size during preprocessing. No cap, that's the whole reason 😭✨
