✨ gnutls_x509_ext_export_tlsfeatures ✨

okay bestie, buckle up 💖 this one lives in the gnutls manual, section 3 — yes, the gnutls library, the TLS icon itself 👑. It's a lil API function and it's lowkey the moment your TLS features struct gets its glow-up into actual wire format. Let's go 🦋

NAME 💅

gnutls_x509_ext_export_tlsfeatures — bestie, it's an API function. That's the whole vibe.

SYNOPSIS 🌸

#include <gnutls/x509-ext.h>

int gnutls_x509_ext_export_tlsfeatures(gnutls_x509_tlsfeatures_t f,
gnutls_datum_t * ext);

like. look at her. so clean ✨

ARGUMENTS 🎀

  • gnutls_x509_tlsfeatures_t f — the features structure. your little bundle of TLS feature joy, the thing you're about to export 🫶
  • gnutls_datum_t * ext — the DER-encoded extension data goes here. and listen: it must be freed using gnutls_free(). not free(), not vibes, not hopes and dreams. gnutls_free(). periodt 💀

DESCRIPTION 🦋

so what does she actually do? this function converts the provided TLS features structure — structure — (yes, the original says it twice, and honestly? iconic, she's emphatic) into a DER-encoded TLS features PKIX extension 🔥

and the output data in ext? that gets allocated using gnutls_malloc() 💖 so it's gnutls's memory, gnutls's rules, gnutls's cleanup. iykyk.

RETURNS ⭐

  • on success, you get GNUTLS_E_SUCCESS (0) 🎉 slay
  • otherwise? a negative error value 😭 so like. check it. please. for me. 🙈

SINCE 🌈

3.5.1 — she's been here since 3.5.1, an elder, a legend, a main character who predates half your dependencies 💜
