✨ gnutls_x509_crt_get_signature ✨

okay bestie, so this is a page from the gnutls manual, and today's main character is gnutls_x509_crt_get_signature — she's an API function and she's here to pull the signature field out of a certificate for you. no cap. 🎀

---

🌸 NAME 🌸

gnutls_x509_crt_get_signature — the API function that gets the signature off a cert 💅

---

🦋 SYNOPSIS 🦋

#include <gnutls/x509.h>

int gnutls_x509_crt_get_signature(gnutls_x509_crt_t cert, char * sig,
       size_t * sig_size);

---

💖 ARGUMENTS 💖

• gnutls_x509_crt_t cert — this one should contain a gnutls_x509_crt_t type. that's the whole vibe. it's your certificate, your girl, your icon. 👑
• char * sig — a pointer to where the signature part is gonna get copied. and yes, she may be null — lowkey chill like that. 🙈
• size_t * sig_size — this one starts out holding the size of sig. so like, she already knows how much room she's working with before anything even happens. respect. ✨

---

🔥 DESCRIPTION 🔥

so what does she actually do? this function will extract the signature field of a certificate. that's it, that's the whole job, and she does it flawlessly. the way that a function can just... do exactly one thing and do it well?? obsessed. 💜

---

⭐ RETURNS ⭐

on success, GNUTLS_E_SUCCESS (0) is returned. anything else and you get a negative error value — so if you see a negative number, that's not a vibe, that's a problem. 😭
