✨ gnutls_session_set_data ✨

okay bestie, welcome to the gnutls manual 💖 this lil page is gnutls_session_set_data(3) and it's lowkey one of the most useful glow-ups in the whole session-resumption saga. sit down, grab a strawberry 🍓, we're doing this.

🌸 SYNOPSIS 🌸

#include <gnutls/gnutls.h>

int gnutls_session_set_data(gnutls_session_t session, const void *
session_data, size_t session_data_size);

🎀 ARGUMENTS 🎀

  • gnutls_session_t session — bestie this is literally just a gnutls_session_t type. that's it. that's the vibe.
  • const void * session_data — a pointer to the space that's gonna hold the session 🫶
  • size_t session_data_size — the size of that session, no cap

👑 DESCRIPTION 👑

so the way this works: it sets all the session parameters, so you can resume a session you already established earlier. iconic behaviour, truly main character energy ✨

the session data you hand over must be the exact stuff that came back from gnutls_session_get_data(). don't be out here freelancing with random bytes 💀

and like, call this function before gnutls_handshake(). before. periodt. 🙈

okay important heads-up bestie: session resuming is advisory. the server is fully allowed to look at your cute little resume request and go "nah". if that happens, a full handshake gets performed instead. not me being ignored by the server 😭 it's giving unread message.

💅 RETURNS 💅

if it slays: GNUTLS_E_SUCCESS (that's 0) comes back to you 🥳

if it doesn't: you get an error code instead. vibe check failed, but at least you know.
