ocs_hcu_hash_init(9)

💖 NAME 💖

okay so bestie, this is ocs_hcu_hash_init(9) from the Kernel API Manual, and its whole job is: Initialize hash operation context. That’s the tea ☕✨

🦋 SYNOPSIS 🦋

int ocs_hcu_hash_init (struct ocs_hcu_hash_ctx *ctx , enum ocs_hcu_algo
algo );

🌸 ARGUMENTS 🌸

• ctx — the context to initialize. It’s the struct ocs_hcu_hash_ctx *, bestie, and she is getting set up 💅
• algo — the hashing algorithm to use, as an enum ocs_hcu_algo. pick your fighter 🎀

🔥 RETURN 🔥

0 on success, negative error code otherwise. So if you get 0, celebrate; if it’s negative, that’s the kernel saying “not today” 😭
