LIBKECCAK_STATE_COPY(3)

📦 version 1.4.3, in arch rolling, opensuse-leap 16.0

okay so bestie, we're in LIBKECCAK_STATE_COPY(3) from the Library Functions Manual, and this is the tiny but iconic copy function that deserves main character energy ✨💅

✨ NAME ✨

  • libkeccak_state_copy — copies hash state, and yes that's the whole vibe 🫶

🦋 SYNOPSIS 🦋

#include <libkeccak.h>

int libkeccak_state_copy(struct libkeccak_state *dest, const struct libkeccak_state *src);

Link with -lkeccak.

🌸 DESCRIPTION 🌸

So libkeccak_state_copy() initialises *dest to be identical to *src — like, a full copy-paste glow-up, no cap 💖

This includes all members of the struct libkeccak_state structure, including the state of the sponge and the message chunk buffer. Every little detail gets copied, bestie — the whole struct is giving matched-set energy 🎀

💖 RETURN VALUES 💖

  • It returns 0 upon successful completion — slay, we love a clean exit ✨
  • On error, -1 is returned and errno is set to describe the error 😭

😭 ERRORS 😭

The libkeccak_state_copy() function may fail for any specified for the function malloc(3). Yep, it's got the same failure energy as malloc(3) — no extra lore, just that 💀
