✨ NAME ✨

gnutls_hex_encode — bestie, it's an API function 💖

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

int gnutls_hex_encode(const gnutls_datum_t * data, char * result, size_t * result_size);

🎀 ARGUMENTS 🎀

  • const gnutls_datum_t * data — this is the raw data, the actual stuff, the un-encoded tea before it gets dressed up 🫖
  • char * result — the spot where the hex data is gonna get copied. Your lil destination. The runway 💅
  • size_t * result_size — this holds the size of the result, and yes it's a pointer, so it's both telling you the size and getting updated, main character energy tbh ✨

🦋 DESCRIPTION 🦋

Okay so basically: this function takes the data you gave it and converts it into printable data using hex encoding, exactly the kind used in the PSK password files. No cap, that's the whole vibe 🔥

Heads up bestie: the size of the result includes the null terminator. The \0 is part of the count. Don't forget them, or the vibe check will fail 😭

🌈 RETURNS 🌈

  • GNUTLS_E_SHORT_MEMORY_BUFFER — when the buffer you handed over is not long enough. Not me giving it a tiny buffer... 💀
  • 0 — on success! Slay, we ate 👑
