GNUTLS_X509_CRL_GET_EXTENSION_DATA(3)

✨ NAME ✨

gnutls_x509_crl_get_extension_data — bestie, this is an API function 💖 (and yes, we're in the gnutls manual, welcome to the group chat 🫶)

---

🌸 SYNOPSIS 🌸

#include <gnutls/x509.h>

int gnutls_x509_crl_get_extension_data(gnutls_x509_crl_t crl, unsigned
indx, void * data, size_t * sizeof_data);

---

🎀 ARGUMENTS 🎀

• gnutls_x509_crl_t crl — okay so this one should contain a gnutls_x509_crl_t type, that's literally its whole job 💅
• unsigned indx — tells it which extension OID to send. Start with (0) to get the first one, like the very first slide of the carousel ✨
• void * data — a pointer to a structure that'll hold the data (may be null, no pressure, she's flexible 🙈)
• size_t * sizeof_data — initially holds the size of oid 🦋

---

💜 DESCRIPTION 💜

So this function will return the requested extension data in the CRL. The extension data gets stored as a string in the buffer you handed over. Iconic behaviour, honestly 👑

Use gnutls_x509_crl_get_extension_info() to extract the OID and the critical flag. And listen — use gnutls_x509_crl_get_extension_info() instead if you want to get data indexed by the extension OID rather than by sequence. Different vibe, different function, iykyk 🔥

---

⭐ RETURNS ⭐

On success, GNUTLS_E_SUCCESS (0) is returned — slay. Otherwise you get a negative error code because something went wrong 😭. And if you've reached the last extension available, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned. That's not a bug bestie, that's just the end of the line 🚫

---

🦋 SINCE 🦋

2.8.0 — she's been around a while, a true veteran 💀
