✨ gnutls_psk_set_params_function(3) ✨

okay bestie, welcome to the gnutls manual, page for gnutls_psk_set_params_function. it's giving niche-but-iconic, fr fr 💅

---

🌸 NAME 🌸

gnutls_psk_set_params_function — an API function, no cap 👑

---

🦋 SYNOPSIS 🦋

#include <gnutls/gnutls.h>

void gnutls_psk_set_params_function(gnutls_psk_server_credentials_t res,
                                    gnutls_params_function * func);

---

💖 ARGUMENTS 💖

• gnutls_psk_server_credentials_t res — literally a gnutls_psk_server_credentials_t type. that's the vibe, that's the whole thing 🫶
• gnutls_params_function * func — the function that's gonna get called. the callback. the main character ✨

---

🎀 DESCRIPTION 🎀

so what this does is it sets a callback, right? and the whole point is that the server uses that callback to get the Diffie-Hellman or RSA parameters for PSK authentication. that's it, that's the job 💜

and heads up: the callback should return GNUTLS_E_SUCCESS (which is 0) on success. zero. that's the good number. that's the slay number 🍓

---

💀 DEPRECATED 💀

not me having to tell you this but bestie… this one is deprecated. 😭

This function is unnecessary and discouraged on GnuTLS 3.6.0 or later. like, please don't. 🙈

Since 3.6.0, DH parameters are negotiated following RFC7919. so the whole callback thing is just… not needed anymore. the library handles it. periodt. ✋
