LIBKECCAK_HMAC_DUPLICATE(3)

✨ NAME ✨

LIBKECCAK_HMAC_DUPLICATE(3) — omg hiii bestie, this is the Library Functions Manual page for libkeccak_hmac_duplicate, and it does exactly one iconic thing: allocate a duplicate of an HMAC-hashing state. 💅

🦋 SYNOPSIS 🦋

#include <libkeccak.h>

struct libkeccak_hmac_state *libkeccak_hmac_duplicate(const struct libkeccak_hmac_state *src);

Link with -lkeccak. 🔗

🌸 DESCRIPTION 🌸

okay so libkeccak_hmac_duplicate() allocates a brand-new hash state and initialises it to be identical to *src. and bestie, “identical” is not a vibe-only promise here: it includes all members of the struct libkeccak_hmac_state structure, including the state of the sponge and the message chunk buffer. full twin energy, no cap. 🫶

🎀 RETURN VALUES 🎀

on successful completion, libkeccak_hmac_duplicate() returns a newly allocated libkeccak_hmac_t* (of one initialised element). on error, NULL is returned and errno is set to describe the error. that's the error signal, bestie. 😭

💀 ERRORS 💀

libkeccak_hmac_duplicate() may fail for any of the reasons specified for the function malloc(3). that's the whole error list, fr fr. 🙈
